Preinstalled but Not Safe. OnePlus OEM App Session Takeover Vulnerability (opens in a new tab)

Doyensec ·10 Sep 2026 ·fetched 10 Sep 2026, 11:39 UTC Research agreed3/3

Why readA live, unpatched session takeover in an app preinstalled on the OnePlus 13R, published after the vendor stopped giving a remediation timeline.

Doyensec targeted the OEM applications shipped on the OnePlus 13R and found a flaw in one of them that allows takeover of a user session. The vendor did not commit to a fix schedule through the disclosure window, so the researchers published without a patch available. Beyond the bug itself, the write up is a concrete case study in what happens when a bug bounty relationship breaks down on the vendor side.

ZDI-26-649: (Pwn2Own) OpenAI Codex Improper Neutralization of Control Sequences Remote Code Execution Vulnerability (opens in a new tab)

ZDI Published Advisories ·10 Sep 2026 ·fetched 10 Sep 2026, 15:41 UTC Research CVE-2026-19591 EPSS 0.3% agreed3/3

Why readCVE-2026-19591: opening a malicious folder in OpenAI Codex gives arbitrary code execution as the current user via control sequences in git command arguments.

A Pwn2Own entry from Compass Security researchers found that Codex insufficiently neutralises control sequences when parsing arguments passed to git, so a crafted repository or directory triggers code execution in the user's context when opened. OpenAI has shipped a fix. EPSS is negligible at 0.003, but the class matters: cloning untrusted repos into an AI coding agent is now a code execution path, and developer workstations are where the credentials live.

ZDI Published Advisories ·9 Sep 2026 ·fetched 9 Sep 2026, 23:38 UTC Research CVE-2026-13086 EPSS 0.4% agreed3/3

Why readUnauthenticated stack buffer overflow in WatchGuard FireWare OS Endpoint Protection Manager gives root code execution to a network-adjacent attacker.

CVE-2026-13086 sits in the Endpoint Protection Manager service in WatchGuard FireWare OS, which copies user-supplied data into a fixed-length stack buffer without validating its length. Exploitation requires no authentication and runs code as root on the firewall itself. EPSS is still low at 0.0044, but an unauthenticated root RCE on a perimeter appliance is the class of bug that gets weaponised after the patch diff is public, so treat the vendor update as urgent.

Why readCVE-2026-86218 is an actively exploited pre-auth RCE in N-able N-central with a CVSS of 10.0, and Hotfix 4 (2026.3 HF4) supersedes every earlier hotfix, so HF3 systems are still vulnerable.

N-able shipped 2026.3 HF4 for CVE-2026-86218, an exploited pre-auth RCE zero-day in on-premises N-central; hosted NCOD instances are already patched. Separately, Huntress built a working PoC for a distinct chain, CVE-2026-86206 and CVE-2026-86207, that bypasses access controls to create unauthorised administrative accounts, addressed in 2026.3.1.13. Operators should apply HF4 now, audit user lists for anomalous accounts such as those with .invalid email addresses, and restrict inbound access to the console. An RMM platform reachable from the internet makes this a downstream-tenant problem, not just a local one.

Why readChaining CVE-2026-86206 and CVE-2026-86207 lets an unauthenticated remote attacker create a System administrator account on N-able N-central, the RMM platform MSPs use to reach every downstream client.

Rapid7's Stephen Fewer found two new flaws while researching the earlier N-central bypass CVE-2026-18577: CVE-2026-86206, a semicolon/Forwarded header access-control bypass (CWE-791, CVSSv4 6.9), and CVE-2026-86207, a UserTwoFactorLogin authentication bypass (CWE-305, CVSSv4 7.7). Chained, they defeat authentication entirely and yield a new attacker-controlled administrator on the latest N-central release. Both are fixed in N-central 2026.3 Hotfix 3; the individual CVSS scores badly undersell the chain given N-central's position in MSP estates.

Why readUnauthenticated remote code execution as SYSTEM in the Windows IKEEXT service via an integer underflow in AES-GCM decryption, CVE-2026-50696.

The IKEv2 handler in IKEEXT fails to validate user-supplied data during AES-GCM decryption, producing an integer underflow before a memory write. No authentication is required, and successful exploitation runs code as SYSTEM, though only hosts with particular IPsec configurations are affected. Worth an inventory pass over anything terminating IPsec on Windows; EPSS is currently 0.012, so patch state rather than observed attacks is the driver.

Why readutil-linux through 2.41.5 and 2.42.2 runs post-mount hooks without checking the mount helper's exit status, so an unprivileged user can abuse X-mount.idmap or X-mount.owner to escalate privileges on pre-existing filesystems.

When the helper fails, mount proceeds to the hooks anyway and applies them to whatever is already at the target, letting an attacker clone a filesystem with inherited suid bits or rewrite target inode permissions. This is local privilege escalation in a package present on essentially every Linux host, including containers and CI runners where user-invocable mounts exist. Distribution updates are the fix; in the meantime audit fstab entries carrying the user option alongside X-mount.idmap or X-mount.owner.

Why readPREVAIL models writes through a T_CTX base register as a no-op, giving a full arbitrary-read primitive in a program the verifier declares safe.

do_mem_store in src/crab/ebpf_transformer.cpp only models T_STACK stores and the checker's T_CTX bounds arm never tests AccessType::write, so a program can overwrite a context field such as ctx->data, reload it typed as T_PACKET, and dereference an attacker-controlled address. The verifier reports the program as safe throughout. Fixed in 0.2.4, and paired with CVE-2026-53670 it makes the case for treating verifier soundness as its own attack surface wherever unprivileged BPF loading is allowed.

Why readA soundness bug in the PREVAIL eBPF verifier accepts out-of-bounds memory access, meaning a malicious BPF program passes verification.

EbpfTransformer::add() silently skips offset-variable updates when the destination register carries a non-singleton typeset, two or more simultaneously possible pointer types, so later bounds checks run against a stale offset. A crafted program is verified as safe and then corrupts memory at runtime. Patched in 0.2.4; PREVAIL is the verifier behind eBPF for Windows, so this is a trust-boundary failure rather than a memory bug in ordinary code.

Why readAn anonymous POST to J2Store's PayPal IPN listener moves a pending order to CONFIRMED with no payment, because _validateIPN() treated UNVERIFIED as valid and stored its verdict where nothing downstream read it.

In J2Store 1.0.0-3.3.21, 4.0.0-4.0.21 and 4.1.0-4.1.6 the IPN listener accepted any non-INVALID response as valid, made its verification callback with CURLOPT_SSL_VERIFYPEER disabled, and continued processing regardless. The amount comparison only ran when mc_gross was a positive number, so omitting the field entirely skipped it, and sequential order ids in the custom field made targeting trivial, including forcing another customer's pending order to FAILED. paypalv2.php performed no amount check at all, so any shop on these versions has been taking free orders for anyone who bothered to look.

Joro's default proxy exposes an unauthenticated local API on 127.0.0.1:9090 with a wildcard CORS policy, and plugin upload uses multipart/form-data, a CORS-safelisted content type that needs no preflight. Cross-origin JavaScript can therefore upload a native plugin and trigger a restart through the operator's browser, and plugins execute on load, yielding RCE as the operator from a single page visit.

Why readUnauthenticated worker exhaustion in Erlang/OTP inets httpd: a chunk-size line that is not hex, delivered in a separate write, permanently leaks the connection's worker.

When a chunked request body arrives in the same write as the headers, httpd_request_handler:handle_body/3 catches the {error, {chunk_size, _}} throw from http_chunk:decode_size/4 and returns 400. Split the chunk-size line into a later write and the decoder resumes through a bare catch in handle_info/2, which turns the throw into a return value that is then treated as the next decoder continuation, so the worker is never released and no timeout reclaims it. Default configuration is affected and no authentication is required, so repeating the request across connections consumes every worker.

httpd_manager:handle_new_connection/4 reads max_clients with the two-argument httpd_util:lookup/2, which returns the atom undefined when the option is unset, rather than the three-argument form carrying the 150 default used by neighbouring code. Erlang term ordering puts every integer before every atom, so the Count =< Max guard always holds and {reject, busy} is never returned. Any inets httpd that relies on the documented default accepts unlimited simultaneous connections, each holding a worker process and a socket, with no request and no authentication needed.

Why readAttribute injection in @xmldom/xmldom below 0.8.14 and 0.9.11: setAttribute() skips QName validation and the serializer emits the name verbatim, so a crafted name injects event handlers into browser-consumed XML.

Element.setAttribute() routes through the private _createAttribute(name) path without name validation, unlike Document.createAttribute(name) which checks against QName. XMLSerializer.serializeToString() then writes the name as given, and requireWellFormed: true did not catch it, so an attacker-controlled attribute name can terminate the intended attribute and inject further attributes including event handlers; synthesized xmlns:PREFIX declarations hit the same unchecked boundary. Fixed in @xmldom/xmldom 0.8.14 and 0.9.11, with no fix for the legacy xmldom package at 0.6.0 and earlier, which means dependency trees pinned to the old package name need migrating rather than bumping.

Why readSlowloris by design in Erlang/OTP inets httpd: the request timeout is cancelled once headers parse, so a stalled body pins a worker forever across OTP 17.0 to 27.3.4.17.

httpd_request_handler:handle_info/2 cancels the request timeout as soon as any parse step succeeds, headers included, and the more-data clause re-arms the socket with {active, once} without setting a new timer. httpd_request:whole_body/2 returns that continuation whenever received bytes fall short of the announced Content-Length, so a well-formed request that stops mid-body leaves the worker blocked indefinitely; the byte-rate reclaim only runs when minimum_bytes_per_second is configured, which it is not by default. Repeating across connections fills max_clients at negligible bandwidth cost. Fixed in OTP 27.3.4.17 and later branch releases.

Project.AddFile, EditFile, RemoveFile and Project.Edit in cmd/server/api/project/handler.go take a row id straight from the JSON body, and model.ProjectFile.GetData and model.Project.GetData filter only on that id, with no namespace ownership check. A user with the manager role or FileSync/EditProject permission in their own namespace can therefore read, write and delete files in any project on the install, and set a foreign project's git remote to a repository they control; Edit runs git remote set-url, so the next deploy pulls attacker code.

Why readTraefik's HTTP/3 server was built with no timeout at all, so the default 60-second read timeout never applies and an unauthenticated client can pin upstream connections open indefinitely.

Bishop Fox found that Traefik's documented request read timeout is implemented as a deadline on the underlying TCP connection, which HTTP/3 does not use; the HTTP/3 server was constructed without any timeout, so the setting has no effect on that protocol. An unauthenticated remote user can hold requests open indefinitely, consuming one upstream connection per request until legitimate traffic is denied.

Why readA Wazuh worker node will write cluster-synced files anywhere under /var/ossec, giving root RCE to anyone holding the cluster key, and it is an incomplete fix for CVE-2026-30893.

In 4.4.0 through 4.14.6, the non-merged branch of update_master_files_in_worker() derives destinations from safe_join() alone, which keeps files inside /var/ossec but never checks they land in the directory declared by their cluster_item_key. The destination check that exists on the primary node and on the worker's merged branch was omitted, so a peer with the cluster key can drop files into paths executed as root; the delete branch has the same gap. This is the residue of CVE-2026-30893, which only blocked traversal outside /var/ossec. Fixed in 4.14.7, and worth prioritising because the cluster key is a shared secret many deployments treat casually.

EPSS sits at 0.003 and the install base is small, so this is a read for robotics and OT teams rather than a general patch scramble.

Why readA validate-on-registration, never-on-use webhook design in Hi.Events yields full-read SSRF to cloud metadata via redirects and DNS changes.

NoInternalUrlRule in backend/app/Validators/Rules/NoInternalUrlRule.php resolves the hostname with gethostbyname() and blocks private ranges only at registration time; WebhookDispatchService then calls the stored URL through spatie/laravel-webhook-server with no Guzzle options set, so redirect following stays on and the resolution is never repeated. A destination that redirects to loopback, RFC1918 or the cloud metadata endpoint, or whose DNS record simply changes later, gets fetched by the server, and WebhookResponseHandlerService stores the response body where the requester can read it back from the webhook logs endpoint. The pattern generalises well beyond this product: SSRF filters that run at configuration time and not at dispatch time are not filters.

BlobOperations.downloadBlobToFile built its local target with new File(fileDir, client.getBlobName()) and handed it straight to the Azure SDK with no lexical normalization and no check that the resolved path stayed under fileDir; because BlobConsumer.createBatchExchangesFromContainer enumerates the container and uses BlobItem.getName() verbatim with no default filtering, the traversal path is not route-controlled data.

Any workflow using actions/upload-artifact@v4 or download-artifact@v4 starts an HTTP backend whose CreateArtifact, GetSignedArtifactURL, ListArtifacts, FinalizeArtifact and DeleteArtifact RPCs accept a caller-supplied workflow_run_backend_id without verifying ownership: validateRunIDV4 in pkg/artifacts/artifacts_v4.go parses the value and returns it with the comparison left commented out. Signed URLs are authenticated with an HMAC keyed on the constant 0xba 0xdb 0xee 0xf0, identical in every build, computed over an unseparated concatenation of endpoint, expiry, artifact name and task ID, so signatures are both forgeable and ambiguous across differing name and task pairs. Because --artifact-server-addr defaults to the outbound interface rather than loopback, anyone on the same network as a developer running act can read, overwrite or delete artifacts.

With publicPath set to /assets and no trailing slash, a request for /assets../.env passes the guard because its dot-dot lives inside the segment "assets..", and the fixed-offset slice hands "../.env" to path.join.

CliprdrStream_Read in libs/clipboard/src/windows/wf_cliprdr.c requests cb bytes of a remote file, then runs CopyMemory(pv, clipboard->req_fdata, clipboard->req_fsize) where req_fsize comes verbatim from the peer's CLIPRDR FileContentsResponse cbRequested field via wf_cliprdr_server_file_contents_response and is never clamped to cb. The only length check, req_fsize < cb, handles short reads and is evaluated after the copy has already happened, so a malicious peer answering a small read with an oversized response writes chosen data past the heap buffer of the OLE paste consumer, typically explorer.exe. Triggering it needs the local user to paste remote clipboard file contents, and since the code is a FreeRDP fork, other downstream forks are worth checking for the same pattern.

DJI drones exchange DUML protocol messages with the DJI Fly app over unencrypted BLE, including the Wi-Fi credentials handed over when a client connects over Wi-Fi or the drone enters QuickTransfer mode. An attacker in BLE range captures the SSID, PSK and trusted-identifier UUID in cleartext, then joins the drone's internal network, reaches its exposed services, and decrypts traffic between the drone and its legitimate operator. Replaying the captured UUID bypasses the physical confirmation step for new devices, so the pairing control provides no real assurance.

Why readAn Expat out-of-bounds read introduced by the fix for CVE-2026-66046, affecting everything through 2.8.3 and reachable through external entity parsers.

A struct size mismatch between ELEMENT_TYPE members causes storeAtts to read the attIndex member past the allocation when parsing XML through parsers created with XML_ExternalEntityParserCreate. The result is either failure to normalise whitespace in non-CDATA attributes or a wild pointer dereference and segfault. That it is a regression from an earlier security fix matters operationally: anyone who patched CVE-2026-66046 promptly is the population now exposed, and Expat is linked into a very wide range of language runtimes and applications.

Why readdbx-web's auth middleware waves through every protected request when password_hash is None, and the service binds 0.0.0.0:4224 by default, so a fresh deploy with DBX_PASSWORD unset is an open SQL execution endpoint.

CVE-2026-55642 pins the flaw to auth_middleware in crates/dbx-web/src/auth.rs: with no stored password and DBX_PASSWORD unset, the middleware passes requests straight to the handler chain. Because crates/dbx-web/src/main.rs binds to all interfaces on port 4224, an unauthenticated attacker can hit /api/connection/connect and /api/query/execute and run arbitrary SQL against the configured databases. Fixed in 0.5.51; the Tauri desktop build is unaffected because it binds loopback only.

In Gotenberg 8.32.0 and earlier, pkg/modules/api/context.go sanitises multipart filenames with filepath.Base, which does not treat backslashes as separators on Linux. The original name flows through ctx.diskToOriginal into archives.FilesFromDisk and archives.Zip.Archive as the zip entry name, so a submitted or downloadFrom Content-Disposition value such as ........\Windows\System32\evil.pdf becomes an arbitrary file write when a downstream Windows extractor unpacks the archive.

CVE-2026-53451 chains three unauthenticated Socket.IO operations in the browser-based Ground Station satellite suite. The save-waterfall-snapshot handler passes attacker-controlled snapshotName from backend/handlers/entities/sdr.py into backend/server/snapshots.py, where os.path.join accepts absolute paths and traversal and writes base64-decoded bytes anywhere on disk; the attacker drops a logging YAML containing a logging.config.dictConfig callable factory, points log_config at it via update-app-config, and calls restart_service so backend/common/logger.py executes it with service privileges.

In phpMyFAQ before 4.1.7 the login challenge produced by prepareForLogin is never written back to the database, because neither WebAuthn controller saves the mutated key objects. The anti-replay comparison then short-circuits on its own null guard, so anyone who captures one successful assertion can replay it indefinitely and authenticate as that user with no interaction. It is a clean example of a passkey deployment losing its replay protection to a missing persistence call, and worth reading if you review WebAuthn implementations.

Algernon before 1.17.9 picks its file handler in engine/handlers.go using filepath.Ext() without rejecting NTFS-equivalent names, so an unauthenticated request for a .lua, .tl, .po2, .amber or .frm script suffixed with ::$DATA, a trailing dot, or a trailing space skips the renderer and execution paths and falls through URL2filename to FilePage, os.Open and ToClient. NTFS resolves the alias back to the real script, so the server returns source code that can carry database credentials, API keys and SetCookieSecret, the last of which permits forged session cookies. Windows hosts only; Linux and macOS are unaffected. Fixed in 1.17.9.

In phpMyFAQ before 4.1.7 the TOTP failure counter is session-scoped, and re-authenticating with the (already known) password issues a fresh session cookie that zeroes it. An attacker holding valid credentials can therefore guess TOTP codes without bound, defeating the second factor entirely. SSVC records a public proof of concept. Worth reading as a pattern to check in your own rate limiting: counters keyed to a session or cookie rather than to the account or the second-factor secret.

CVE-2026-8452 is a heap overflow in the SAML single sign-on parser on Citrix NetScaler ADC and Gateway, reachable pre-authentication in one HTTP request against any Gateway or AAA vserver with SAML configured, and it corrupts memory in the process handling all appliance traffic. Bishop Fox worked out that patch state is observable from the outside in one or two ordinary SAML exchanges, and released a checker covering both directions of the exchange, which matters because upgrading the build does not guarantee every virtual server picked up the fix. The post also lays out compromise indicators to hunt for and flags a crash signature that practitioners are likely to misread as evidence of an attack.

Nebula through 1.2.0 reads out of bounds in Vlp32Decoder::unpack() when a datagram shorter than expected arrives on the Velodyne UDP sensor port, which unlike the other drivers applies no sender-address restriction. The decoder walks into adjacent heap memory and silently emits fabricated points into downstream PointCloud2 messages consumed by Autoware nodes, so the consequence is data integrity in a perception stack rather than a crash (CVSS 4.0 VI:H).

Why readData::MuForm::Localizer through 0.05 executes Perl taken from a message catalog Plural-Forms header, reachable at an arbitrary path via traversal in the language attribute.

load_lexicon builds the catalog path as Messages/$lang.po relative to Localizer.pm without checking that $lang is a bare locale tag, so ../ segments load any readable .po file. extract_header_msgstr then prefixes $ to nplurals, plural and n in the Plural-Forms header and evaluates the remainder, so a header of nplurals=2; plural=(system('...'),0); runs a command at catalog load time. Anywhere the language attribute is user-influenced, this is remote code execution.

Why readAn unauthenticated attacker can register their own ML-KEM-768 public key as an extra recipient for any tenant's encrypted appointments, and a JavaScript `undefined === undefined` comparison makes the bypass silent.

OpenReception before 1.0.4 accepts attacker-supplied ML-KEM-768 public keys at POST /api/tenants/{tenantId}/staff/{staffId}/crypto without authentication: the handler logs an "Unauthorized crypto key storage attempt" warning when neither session nor registration cookie is present, then inserts the row anyway. That breaks the platform's claim that even administrators cannot read sensitive data, since the attacker becomes an additional decryption recipient for future patient appointments. A second variant suppresses even the warning: the Zod schema marks `email` optional, so omitting it with no registration cookie makes the check `registrationEmail === email` evaluate `undefined === undefined` to true and the request is treated as legitimate.

In OpenReception before 1.0.2, POST /api/auth/register/{userId} checks that the WebAuthn challenge matches the registration cookie's email but never checks that the path `userId` belongs to that email. An attacker requests a challenge for their own address, completes the ceremony with their own authenticator, and replays the response against a victim's user ID; addPasskey writes the attacker credential into the victim's user_passkey rows and the next login as the victim's email issues them a session.

OpenReception before 1.0.1 never checks whether an administrator already exists when handling POST to /setup/create-admin-account, so any unauthenticated party who can submit a same-origin form POST creates a new platform admin. The account is written with is_active=true and confirmation_state=ACCESS_GRANTED, skipping email confirmation and usable immediately for login and tenant enumeration. This is separate from the documented deploy-to-claim race: the protecting layout guard only redirects on GET, so the hole persists after the operator has properly claimed the instance.

Why readUnauthenticated blind SSRF in Ground Station before 0.6.0 that reaches cloud instance metadata at 169.254.169.254 from an open Socket.IO listener on port 7000.

Authentication enforcement is disabled and CORS is wildcarded on the Socket.IO server, so any client can send a data_submission event with the submit-orbital-sources action to persist an attacker-chosen URL, then fire background_task:start to make the process fetch it. The URL goes straight to requests.get in _fetch_http_3le and _fetch_http_omm in backend/tlesync/source_adapters.py with no scheme allowlist and no rejection of loopback, RFC1918 or link-local addresses. Outbound status codes and error strings are broadcast back over the orbital_sync_state event to every connected client, turning the blind SSRF into a usable internal port scanner.

Why readAny page that can reach a developer's Vite HMR port can chain two unauthenticated Nuxt DevTools RPC calls into arbitrary command execution on that developer's machine.

Nuxt DevTools before 3.3.1 exposes a bidirectional RPC channel over the Vite HMR WebSocket (subprotocol vite-hmr) with no token, handshake, or origin check. updateOptions(), clearOptions(), and openInEditor() skip the ensureDevAuthToken check the other mutating methods enforce, so an attacker sets behavior.openInEditor to an arbitrary command via updateOptions() and then calls openInEditor() on any existing file, at which point the launch-editor package spawns it as a child process. Development mode only, but developer workstations hold cloud credentials and signing keys, and the missing origin check is what makes this reachable from a browser tab.

Why readSignature verification in U-Boot SPL can be bypassed during FIT image processing, giving controlled code execution before the verified boot chain starts.

A flaw in how U-Boot's Secondary Program Loader parses FIT images allows an attacker to get code execution while bypassing image signature checks, defeating verified boot on affected embedded configurations. The exposure is configuration-dependent, so whether a given board is affected turns on how its SPL and FIT setup is built. Upstream boot protections were hardened in response, anyone shipping U-Boot in a device with a root of trust should re-check their SPL config against the disclosed conditions.

ConvertWebsiteToPDF.java validates only that the initially requested URL resolves to a public IP, then fetches the page server-side and hands the raw HTML to a WeasyPrint subprocess. WeasyPrint retrieves embedded resources, `<img src="http://169.254.169.254/...">` and the like, with no per-resource filtering, so internal endpoints and IMDS responses land in the generated PDF. The endpoint requires no authentication, and the html/pdf, file/pdf and markdown/pdf paths were fixed while this one was not, which is the more interesting lesson: SSRF fixes applied per-endpoint rather than in the fetch layer leave gaps.

Why readAn `and`/`or` precedence bug in ESPHome's `cv.url()` validator lets a `file://` URL in `external_components` clone and execute arbitrary local Python.

`if parsed.scheme and parsed.netloc or parsed.scheme == "file"` binds `and` tighter than `or`, so any `file:` URI passes validation regardless of netloc. That validator gates the `url:` field of the `external_components` git source schema, which is handed to `git clone`, git supports `file://` natively, and the cloned path is then registered with Python's import machinery by ESPHome's component loader. Processing a crafted YAML config with `esphome config` or `esphome run` therefore executes attacker Python; affects through 2026.7.0-dev, and shared or downloaded ESPHome configs are common enough in the Home Assistant ecosystem to make this realistic.

Why readMemos validates a webhook's resolved IPs and then dials the original hostname, letting net.Dialer re-resolve it, a clean, reproducible DNS-rebinding TOCTOU bypass of SSRF protection you should check your own code for.

CVE-2026-71272 (CVSS 8.5) breaks down safeDialContext() in internal/webhook/webhook.go: it calls net.DefaultResolver.LookupHost(), checks the returned addresses against reserved ranges, then passes net.JoinHostPort(host, port) rather than the validated IP to the dialer. DialContext performs its own lookup, so an attacker with control of a short-TTL record returns a public IP at validation time and an internal one at connect time. The fix pattern, dial the IP you validated, not the name, generalises to every SSRF guard written this way.

The Lua engine (re/lua.go) validates nothing and preloads `db`, `ioutil`, an HTTP client and `filepath`. The result is arbitrary file read/write, environment-variable disclosure, direct database access and SSRF into internal microservices from an ordinary user account, a good case study in why interpreter-based rules engines need symbol allowlists, not regex denylists.

CVE-2026-71255 (CVSS 8.6) is an out-of-bounds write in recv_read_device_identification_res() (FC 0x2B / MEI 0x0E) in nanomodbus.c.

CVE-2026-71288 (CVSS 8.8) traces the flaw through reports/guided_reports.pl, where multi_param('order_by') and the derived `_ovalue` parameter are appended verbatim to the query in C4::Reports::Guided with no allowlist or escaping. ORDER BY columns cannot be bound as placeholders, so an allowlist is the only defence and none exists. The create_reports or execute_reports permission, routinely granted to non-admin staff at libraries running Koha, is enough for time-based blind extraction of patron records and staff/LDAP credentials.

Live script tags are reconstructed and stored, then rendered elsewhere without re-sanitisation, giving stored XSS across products, recipes, stock, users, chores and other objects. Worth reading as a pattern: post-sanitisation "cleanup" of encoded output is a recurring way to defeat a correct sanitiser.

Why readOne unauthenticated UDP packet to port 5060 overflows a fixed stack buffer in OpenSIPS with attacker-controlled length and content, and no fix existed when the advisory published.

sip_to_json() in modules/sipmsgops/sipmsgops.c memcpys a SIP header name into a 255-byte stack buffer using the full parsed length, while the SIP parser itself permits header names up to roughly 65000 bytes. Any deployment whose routing script calls sip_to_json() can therefore have its saved frame pointer and return address overwritten by a single unauthenticated datagram, giving a reliable crash and, on builds without stack protections, code execution. The affected range is 4.0.0 and prior with no patch at publication, so the immediate control is auditing routing scripts for sip_to_json() and filtering oversized header names upstream.

Why readShows how root on a Kubernetes node lets an attacker spoof cgroup data to make the SPIRE agent hand over another workload's SVID, breaking the trust assumption underneath SPIFFE deployments.

Unit 42 demonstrates post-exploitation identity misuse against SPIFFE/SPIRE: with root on a node, an attacker forges the Linux cgroup information the SPIRE agent reads during workload attestation, so the agent issues a co-located workload's Verifiable Identity Document to an attacker-controlled process. The team built tooling to carry this out, and the conclusion generalises beyond SPIRE, since every machine-identity system rests on the node being trusted. Not observed in the wild, but it reframes what short-lived workload identities actually buy you once node compromise is on the table.

Why readA method for reliably triggering and regression-testing race condition bugs, using memory access tracing plus delay injection keyed on the stack trace at the access site rather than hand-placed mdelay() calls.

Race conditions resist both proof and regression testing: a candidate found by code reading may never interleave the right way, and after a fix there is usually no test that reliably reproduces the original bug. Horn's approach traces memory accesses and injects delays conditioned on the call stack at the accessing instruction, which replaces the usual practice of recompiling a kernel with conditional mdelay() spinloops inserted by hand. The payoff is threefold: confirming or disproving manually discovered bug candidates, writing regression tests that actually hit the interleaving, and steering fuzzers into code paths that only execute while operations are racing.

Part 1 documents the Server Licensor Certificate, the license issuance flow and the service's exposed endpoints, then covers reconnaissance: locating an RMS deployment, identifying an AD RMS-protected file, and following the path toward the SLC private key that underpins all content protection. Useful groundwork for anyone assessing or defending a legacy RMS install ahead of the attack detail promised in later parts.

REDCELL runs a LangGraph plan and act loop in which an orchestrator hands objectives to executor agents that invoke real tooling inside a Kali container, then assembles PDF, JSON and SARIF reports. Models are pluggable through LiteLLM across hosted and local providers, and every run checkpoints so a crash resumes in place. The operator console exposes the agent graph, an activity feed, the driven browser and a terminal on any caught reverse shell, which makes it as useful for evaluating agentic offensive capability as for using it.

Why readApplies conformal prediction to the attacker's side of privacy-preserving ML and network traffic analysis, giving calibrated confidence to membership and traffic-classification attacks rather than to defences.

Conformal prediction has been used almost exclusively defensively in security work; this paper takes it offensive, presenting initial results in two areas: attacks against privacy-preserving machine learning, and network traffic analysis. The framing is that CP's distribution-free coverage guarantees let an attacker quantify how much to trust a given inference, which matters for attacks whose value depends on precision. Explicitly preliminary findings rather than a finished technique, so treat it as a direction worth tracking.

The authors argue this is what modern dynamic, client heavy applications demand, and their evaluation reports substantial improvements in both coverage and vulnerability discovery. The abstraction layer is offered as reusable scaffolding rather than a finished product, which is the more durable contribution for anyone building appsec tooling.

The 20.9% to 39.2% relative improvement over prior work matters mainly because the threat model is the realistic one: an attacker who only sees a verdict. Used for adversarial training it also produces detectors with more generalisable robustness, so it cuts both ways for anyone shipping ML-based detection.

University of Toronto researchers hammered four DRAM banks for 24 hours each across four Ampere-class cards, including the RTX A6000, and induced bit flips on every one, defeating on-die ECC to reach denial of service and privilege escalation to root on the host. The attack needs only the ability to launch an unprivileged CUDA kernel, so a co-tenant on a shared GPU or untrusted code on a single-tenant box qualifies. NVIDIA's response points to System-Level ECC as the mitigation; the practical advice is to avoid cross-tenant GPU sharing, watch ECC error counters, and fence untrusted CUDA workloads.

IOActive traced Signal Desktop's contentProtection feature to the Windows API SetWindowDisplayAffinity, then reverse engineered win32kfull!NtUserSetWindowDisplayAffinity to show the kernel enforces an ownership check that rejects cross-process attempts to disable it, which is why privileged external calls fail. The bypass runs code inside Signal's own process context via CreateRemoteThread, satisfying the ownership check and re-enabling screen capture of the window. The finding generalises to any Electron application relying on display affinity as an anti-capture control, which is worth knowing before you treat that flag as a defence against screen-capturing malware.

Why readIntroduces masked auto-correlation as a cryptanalytic primitive and pairs a constant-query quantum sampling algorithm with a proven classical lower bound of Omega(N/log N) for the same task.

Masked auto-correlation measures the correlation between masked outputs alpha.f(x) and beta.f(x XOR w) for a permutation f, and the resulting masked differential-linear approximations subsume ordinary linear cryptanalysis, differential-linear cryptanalysis and the differential-linear connectivity table as special cases. The authors define 'MAC Fishing', finding mask pairs with large masked cross-correlation, give a constant-query quantum algorithm that samples them proportional to squared correlation, and prove an exponential classical query lower bound by adapting the hardness of Fourier Fishing. It is claimed as the first result pairing a quantum upper bound with a matching classical lower bound in this setting, which makes it a reference point for post-quantum symmetric-primitive margins rather than an immediate break.

The claimed contribution is removing hand-written message builders from cryptographic protocol testing, with protocol security testing case studies as evidence. Useful if you build harnesses for TLS-class or proprietary encrypted protocols; the abstract alone does not show how well the LLM extraction holds up on messy specs.

Variants using attributes[0].value, textContent and nodeValue give fallbacks when one property is filtered, which makes signature-based WAF rules on payload strings unreliable.

Candidates are replayed with URL, method, body and content type intact but Cookie and Authorization headers removed, giving the unauthenticated view of each endpoint. The write up makes a useful operational point for anyone triaging such output: of 88 responses returning HTTP 2xx, 79 carried code: 401 in the body, so status codes alone will badly overcount findings.

The authors held three extensions at pinned older versions, ran Cursor's import, and got all three back at the newest Open VSX version. The workaround is explicit pinning via cursor --install-extension <publisher>.<name>@<version>, and the broader finding is that agentic IDE migration quietly breaks any extension version control a team thought it had.

Why readBuilds the first formal model of WhatsApp Web's Signal protocol implementation and checks live executions against it with a runtime monitor.

The authors instrument WhatsApp Web and Signal Desktop to capture network traffic and calls into the cryptographic components, then express two multiset-rewrite models compatible with Tamarin so observed runs can be checked for conformance to the verified specification. This closes the usual gap between a proved protocol and what the shipped client actually does at runtime. The method, SpecMon-style conformance monitoring against a Tamarin model, transfers to any protocol implementation you can instrument.

The authors tested whether current LLMs can synthesise executable CodeQL queries from National Vulnerability Database entries, evaluating several model architectures against a set of real-world vulnerabilities. Generated queries improved average F1 by 82 percent over the baseline CodeQL suites, and the paper attaches a cost-benefit analysis rather than reporting accuracy alone. This is a defensive tooling result first and an AI result second: the practical question it answers is whether query authoring, historically the bottleneck in static analysis coverage, can be automated at acceptable cost.

Everything is evaluated through one blueprint that tunes parameters per dataset and reports practical attack accuracy, information theoretic leakage and bandwidth or latency overhead side by side. The result is a realistic picture of what application layer traffic shaping buys you without an encapsulating protocol, which matters for anyone weighing privacy protections they can actually ship on a web property.

Their argument is that KATs use fixed seeds and therefore reach fixed loop depths, whereas real signing resamples per message, so the blind spot sits in the instrument rather than in the engineering. They replace the gate with a byte-exact golden reference oracle plus randomized adversarial soak, report 301,343 data-dependent signings with zero escapes, and use that separation of judging from authoring to argue AI-authored RTL becomes an answerable question.

The paper defines policy-relative effect closure: a grant is closed only when no existing authorization retains a path to an effect the application would reject, and no new ones can be issued. EFFECTBOUND reduces the question to finite control with hidden state and returns a strategy, an impossibility certificate, or no verdict when evidence is insufficient, with machine-checked proofs for the reduction and checker soundness. Applied to four real platforms, closure fails three ways: the interface lacks a needed control, clean visible state hides active work, or the model stops before the effect frontier.

Treat it as a design worth borrowing rather than a validated tool; the interesting part is the choice of behavior as the canonical space, not the extraction stage.

Why readBenchmarks the algorithms used to find vulnerability-inducing commits and shows V-SZZ and LLM4SZZ manage only 33-40% F1, so affected-version ranges derived from them should not be trusted.

VICBench provides 100 human-and-agent verified vulnerability-inducing commits for 100 CVEs across 88 Python, Java and C++ projects covering 48 CWE types. The fixes average 38.6 lines and the inducing commits 252.5 lines, substantially more complex than earlier datasets that skewed to single-line changes. State-of-the-art SZZ variants score 33.3-40.1% F1 against it, which is a direct caution for anyone using automated VIC identification to establish which software versions are actually vulnerable.

How Trail of Bits helps verify the integrity of your Signal chats (opens in a new tab)

Trail of Bits ·11 Aug 2026 ·fetched 11 Aug 2026, 19:34 UTC Research agreed2/2

Why readExplains Signal's new Automatic Key Verification key-transparency scheme and the independent third-party auditor Trail of Bits wrote from scratch to check the server is not handing out substituted public keys.

Signal clients have always had to trust the server to return the correct public key for a contact, with in-person safety number comparison the only detection path. Automatic Key Verification builds a globally consistent transparency log over the key set, and its integrity depends on independent auditors continuously checking the log behaves honestly. Trail of Bits built and operates one of the three auditors as a from-scratch implementation, so the post doubles as a practical account of how to run diverse-implementation checks on a key transparency system.

Why readNames the specific Android advertising SDKs that collect and share location by default whenever the host app holds location permission, so you can audit your own dependency list.

An EFF investigation identifies several advertising SDKs that, by their own documentation, collect and share user location by default once embedded in an Android app that has been granted location permission. Developers integrating them for monetisation frequently do not realise the default, and the resulting data flows into the broker market that has fed ICE investigations, commercial spy tooling, and tracking of military personnel and union organisers. Treat ad SDKs as a supply-chain review item: check the default collection posture and the opt-out switches before shipping, not after.

EFF traced the pipeline from mobile apps to location data brokers and found that several ad SDKs share location by default, with revenue incentives and unclear documentation nudging developers toward leaving it on. The consent chain breaks at the developer, not the user: an app team integrating a monetization library can export precise location without ever making a deliberate decision to do so. For appsec and privacy teams, this makes ad SDK configuration a dependency review item, not a product concern.

Why readA Lean 4 framework that turns game-hopping crypto proofs into inspectable formal objects with machine-checked concrete advantage bounds.

HOPSCOTCH models security definitions as indistinguishability between stateful probabilistic oracles and represents a game-hopping argument as an explicit proof object whose constructors mirror the standard hop steps. A general computational soundness theorem interprets that object by building reductions against the assumptions it invokes, yielding a concrete bound on any distinguisher's advantage rather than an asymptotic claim. The shallow embedding, oracles and reductions are plain Lean definitions, lets proofs draw on Mathlib's existing algebra, which is what makes this more usable than earlier mechanization attempts.

Why readCase walkthrough showing a 32GB monolithic SD card that failed to enumerate was a shorted supply rail, not dead NAND, and why diagnosing power before pinout work saves the evidence.

An undetectable monolithic card has at least five candidate failure points: controller, NAND array, embedded power circuitry, external contacts and supporting passives. In this case the card showed no initialization and no interface communication, and the cause turned out to be a shorted supply rail rather than controller or flash failure, meaning direct NAND acquisition would have been unnecessary physical intervention. The takeaway is a triage order for chip-off work: prove the power circuitry before committing to pinout discovery.

An operator running a semi-autonomous coding agent was observed hunting poorly secured LLM resale gateways, taking API access through ordinary web flaws and account farming, validating the capacity and consolidating it behind a single OpenAI-compatible gateway of their own. The capture came from an AI honeypot emulating an inference endpoint that the agent repeatedly selected as a free backend, so the reconstruction is based on the agent's own traffic rather than on downstream reporting. The finding is the feedback loop: stolen inference funds further acquisition, making the supply chain partially self-expanding, which means exposed LLM gateways are now an asset class worth attacking in their own right.

The permutation baseline is the useful part of the methodology, since it tests whether the model is finding real weaknesses or just flagging a lot.

Why readFormalises the obfuscation primitives behind TEE-Shielded LLM Partition schemes and characterises where their security boundary actually sits, rather than leaving each design to be broken individually.

TSLP methods offload heavy layers to an external GPU under obfuscation while keeping lightweight operations in the TEE, and several have fallen to attacks tailored to their specific implementations. This work defines obfuscation primitives as dual-tuples of linear computations with specified properties, unifies prior methods under them, and analyses the security of their compositions so the boundary can be reasoned about instead of assumed. Relevant to anyone shipping on-device model IP protection built on TEE partitioning.

Input privacy comes from LPN-based pseudorandom masking layered on the verification primitive. If the overhead claims hold in the implementation, this addresses the practical objection that has kept verifiable inference academic.

Why readA cache side channel recovers the actual text a locally hosted model generates, and it targets the detokenizer, which is present in every default inference pipeline rather than in some exotic configuration.

The attack uses Flush+Reload on shared tokenizer code to learn exactly when a decode step happens, then times a Prime+Probe window to capture token-dependent cache activity, and feeds the noisy traces through a clustering and language-model pipeline to reconstruct output text. Unlike earlier work it needs no shared data memory, no CPU offloading and no Mixture-of-Experts layout, so it applies to ordinary local deployments including agentic systems. The authors reproduce semantically accurate recovery across several datasets, hardware platforms, inference frameworks and model families, and note that the most widely shipped tokenizer implementations are the vulnerable ones.

HoneyRoute adds deception at the inference-serving tier rather than inside model memory or the protocol layer: a streaming router built on a frozen 0.8B embedding backbone with per-domain MLP heads classifies incoming requests, and malicious ones are diverted to either a prompt-engineered code honeypot or a same-family replica while the interaction is harvested. On a production trace plus a seven-domain attack corpus it matches 96% of a two-tier guard-LLM cascade's F1 at 1/385 of the latency, and trapped interactions feed attacker fingerprints back into router retraining.

On a leak family with closed-form total variation, nine LLM monitors sit at the optimum when TV=0 but average 60.9% at TV=1, where a 20-line membership check scores 100%.

Seven experiments on live shared serving, including vLLM running DeepSeek-R1-Distill-Llama-8B on an NVIDIA GB10, show AUROC dropping from 0.650 at ambient to 0.531 near 61% prefix overlap before partially recovering to 0.574 at saturation. A 120-run sparse-overlap experiment puts the breakpoint at the edge of the measured range (tau=0, 95% CI 0.000 to 0.113), which the authors read as an ambient-versus-loaded regime change rather than a physical threshold. Concurrency-depth variance is the strongest correlate of effect size (r=-0.416), so the practical takeaway is that reported attack reliability from quiet-server experiments overstates what a tenant on a busy endpoint gets.

The insight is that recovering artefacts does not transfer capability, because the weaker agent lacks implicit procedural behaviours; those behaviours are exposed by observable differences between victim successes and attacker failures. If your agent's value is its accumulated procedural knowledge, limited black-box interaction is enough to start extracting it.

With a detector guided policy, the agent redirects budget toward genuine hosts and compromises more of the pool.

Under a pre-registered protocol with an injected known-strength leak, a shuffled-label control and a threshold fixed before the runs, the zero pattern identified all 4,096 real rows on every frame across nine seeds, and content recovery beat a constant-guess baseline by 0.65 to 1.50 percentage points.

CONTINUITY models each component of an LLM agent stack with an assume-guarantee contract and carries authenticated context across transitions using signed root grants, provenance commitments, role-bound transition receipts, bounded typed releases and effect-bound execution permits. The property it enforces, end-to-end consequence integrity, requires every external effect to trace back to a current authorization witness binding principal, task, provenance, delegation and canonical action. A reference implementation exists, though the work is formal rather than an attack against deployed systems.

Forgetting Without Restarting: Execution-State Unlearning for Stateful LLM Agents (opens in a new tab)

arXiv cs.CR (AI) ·Chao Yao, Yangbo Wei, Zhen Huang, Junhong Qian ·7 Sep 2026 ·fetched 7 Sep 2026, 03:42 UTC Research agreed3/3

Why readExplains why a 'forget' on a long-running agent is mostly theatre: deleting the memory record leaves summaries, pending tool plans and the KV cache still tainted.

The paper formalises execution-state unlearning, requiring an agent to behave as if it had never observed the revoked data, and proves that the tainted suffix cannot be repaired without token-level attribution and that exact unlearning needs at least T minus tau plus one recomputed transitions from the injection step. Provenance-Guided Selective Replay hits that bound by locating the injection point in a provenance graph, cropping the KV cache back to a checkpoint, and replaying a sanitised suffix. Relevant to anyone handling deletion requests or credential revocation in stateful agent deployments.

Reporting rates fell as personalization rose while deletion rose, which is the more awkward finding for awareness programmes that measure success by report volume.

Because there is no injected command and no task hijack, the manipulated agent still produces valid output for the requested task, which is precisely what makes review of a skill file inadequate as a control. Tested in agentic commerce and software dependency selection, the two places where a quietly steered choice converts straight into money or into an attacker-chosen package.

Why readUMPeek recovers private user attributes from a personalised LLM agent through ordinary follow-up requests, defeating the assumption that compressed user models are safer than stored raw text.

Personalised agents increasingly compress memory into structured user models, which is commonly treated as privacy-preserving because direct memory-extraction attacks lose the source wording to target. The paper shows the model still leaks through the choices it shapes: UMPeek is a black-box attack that forms hypotheses from ambiguity in a request, probes with ordinary follow-up tasks, and keeps only claims the visible behaviour supports and does not contradict. Benchmarked across personalisation tasks and multiple user-model backends against existing attacks, with real-world validation.

The proposed fix, safety-awareness representation transfer, is a lightweight direction-refinement method that moves refusal signals from the text pathway with the MLLM backbone frozen.

It adds a proximal objective for non-IID clients, domain-balanced aggregation and over-refusal-constrained threshold calibration, evaluated on Agent-SafetyBench and R-Judge.

They also show agents game PoC-only validation by patching along the crash stack trace, passing the check without addressing the underlying bug. PatchBench is proposed as a benchmark that resists both, which matters to anyone currently citing agentic patching pass rates as evidence of capability.

The authors prove the z-score test remains N(0,1) under the null, so detection guarantees match fixed-size green lists. The stateless design permits full-vocabulary self-salt watermarking reported at over 6000x faster than KGW's self-salt and 2x faster than SynthID, and is compatible with distributed inference; the paper also covers hash function design requirements.

The threat model assumes no access to the victim's deployed knowledge base, retriever, reranker or generator, which moves this from a general degradation result to targeted weakness selection.

The practical consequence is that single-turn refusal benchmarks misstate both jailbreak risk and over-refusal against legitimate defenders.

When Safety Routing Breaks: Understanding Alignment Fragility under Benign Fine-Tuning (opens in a new tab)

arXiv cs.CR (AI) ·Yitong Guo, Xiaoyi Chen, Siyuan Zhang, Xiaofeng Wang ·2 Sep 2026 ·fetched 2 Sep 2026, 03:42 UTC Research agreed3/3

Why readExplains why 100 benign fine-tuning examples can collapse safety alignment while barely touching utility, and why LoRA and ASAM only delay it.

The paper argues safety Fisher information is low-rank and that alignment flattens safety geometry while leaving an output-routing pathway intact; benign fine-tuning selectively re-sharpens that pathway in output-side MLP modules. That asymmetry explains both the sharp jump in attack success rate against mild utility loss and why a handful of safety examples restores refusal. LoRA and ASAM suppress output-side sharpness and delay early collapse, but their protection weakens as fine-tuning scale grows.

Why readMeasures how often a cheap verifier model rubber-stamps a cheap student's wrong answers, and shows the blind spot grows as the student gets better.

Testing inference cascades on real models, the verifier's blind-spot rate (wrong student answers it accepts) rises from 0.12 to 0.55 as the student scales from 0.5B to 32B, so the failure is worst in exactly the cheap-student, cheap-verifier setup cascades exist to build. Swapping in a frontier verifier cuts the blind spot to about 0.05 but escalates 46% of hard-MATH queries against a 39% true error rate, erasing the cost saving. Corrective fine-tuning on the verifier-rejected tail degraded and eventually collapsed the small student across every teacher tried, which matters to anyone using an LLM judge as a gate.

Attacks the problem that agents today either hand a peer raw data or accept its unverifiable natural-language claim that a value complies with policy, the latter being precisely the prompt-injection channel. The gateway has agents exchange proofs of governance-defined predicates instead, and because neither MCP nor A2A can carry such a proof, the authors define a slot and implement it on both from a single endpoint.

arXiv cs.CR (AI) ·Ruichen Qi, Xinting Jiang, Ema Dimitrova, Junyi Luo ·29 Aug 2026 ·fetched 29 Aug 2026, 15:38 UTC Research agreed3/3

Why readShows that root-of-trust model verification at load time leaves a TOCTOU window across DRAM, DMA and interconnect, and offers a streaming check at the pre-compute boundary to close it.

Weights authenticated at load can be tampered with in transit to the compute engine while the signed model image stays valid. SILK repurposes the least significant bits of quantized weights as secret-keyed integrity bits, chains dependencies across weight bytes so one local edit perturbs several checks, and gates commits so unverified weights never reach computation. Forgery probability falls exponentially with the number of affected checks under a secure PRF, and measured miss rates track the analytical bound.

SkillShield: Prompt-Space Security Skills for LLM Coding Agents (opens in a new tab)

arXiv cs.CR (AI) ·Xiaodong Wu, Zhimin Zhao, Qi Li, Xiangman Li ·29 Aug 2026 ·fetched 29 Aug 2026, 19:39 UTC Research agreed3/3

Why readA system-prompt-only defence for coding agents that needs no model weights or trajectory monitor, with a comparison of three ways to spend limited prompt budget.

SkillShield synthesises security skills offline from known attacks and recorded agent failures, then injects them into the system prompt at session start so they stay active through the tool-use loop. The interesting part is the budget question: the authors compare all-classes (one skill covering everything), per-bundle (one per related subset) and per-class provisioning under a fixed prompt budget. Relevant to anyone deploying API-only coding agents where weight-level alignment is not an option.

Five Primitives for Governing Autonomous AI Agents at Runtime (opens in a new tab)

arXiv cs.CR (AI) ·Jiten Oswal, John Cadeddu ·29 Aug 2026 ·fetched 29 Aug 2026, 15:38 UTC Research agreed3/3

Why readArgues that governing autonomous AI agents is a runtime problem, not an alignment or build-time one, and names five control primitives: discovery, identity, governance, attestation and supply chain.

Identifies three ways human-user IAM breaks for agents: principals are ephemeral rather than provisioned, their action set is model-selected and so unknown in advance, and the population is discovered because anyone with API access can create one. The proposed implementation mediates each action against policy before it takes effect, authorises it against a per-tenant action vocabulary, and writes it to a hash-linked signed ledger a third party can verify. The five primitives are a position specific enough to design against or argue with, though the evaluation is architectural rather than empirical.

NeuronFuzz: Safety Neuron Guided Fuzzing for LLM Safety Evaluation (opens in a new tab)

arXiv cs.CR (AI) ·Zhiyuan Xu, Muhammad Firhard Roslan, Joseph Gardiner, Sana Belguith ·29 Aug 2026 ·fetched 29 Aug 2026, 19:39 UTC Research agreed3/3

Why readUses safety-neuron activations as continuous fuzzing feedback, dropping response generation from the loop and giving gradient where refusal-only feedback is flat.

NeuronFuzz builds a SafetyOracle by identifying a compact set of safety neurons using template-invariant harmful and benign inputs with stability-aware selection, then converts their activations into a continuous alarm score available at prefill. That removes the expensive generate-then-judge step and provides dense guidance on strongly aligned models where nearly every candidate prompt returns the same refusal. White-box access limits it to teams evaluating models they host.

SecureDrive-FL: Joint Differential Privacy and Gradient-Aware Selective Homomorphic Encryption for Federated Driver Monitoring (opens in a new tab)

Why readSelective homomorphic encryption driven by a differential-privacy sensitivity threshold cuts federated-learning crypto overhead while holding accuracy and poisoning resistance.

GASHE encrypts only gradient components above a DP-calibrated sensitivity threshold instead of applying CKKS to every parameter, and SecureDrive-FL derives the encryption mask directly from DP-SGD calibration to link training-time privacy with in-transit confidentiality. On a ten-class distracted-driver task with non-IID splits it reaches 73.6% accuracy against 74.0% for DP-SGD alone, with a 3.9% attack success rate for both. The threat model is MitM interception of updates plus model poisoning; the contribution is the coupling, not the primitives.

When Context Gets Root: Privilege Escalation in LLM Harnesses (opens in a new tab)

arXiv cs.CR (all) ·Xingbang He, Yuanwei Chen, Yi Qian, Haiyang Wei ·28 Aug 2026 ·fetched 28 Aug 2026, 17:28 UTC Must read Research agreed3/3

Why readShows that agent harnesses themselves break instruction hierarchy by promoting attacker-controlled content into higher-privilege context, hitting all 13 attack objectives including RCE across six coding-agent harnesses.

Instruction hierarchy assumes a model can rank instructions by source, but the harness assembles the context for each invocation and in doing so can elevate low-level content to a higher instruction level. The authors name this instruction privilege escalation and demonstrate it with multi-agent mechanisms against 13 objectives spanning confidentiality, integrity, availability and remote code execution, achieving all 13 on all six harnesses with unrestricted action execution and all 13 on the three harnesses offering automatic permission review. The consequence is that model-side hierarchy defences cannot be trusted without auditing how the harness builds context, which is where the privilege boundary actually lives.

The Framing Gap: Indirect Prompt-Injection Exfiltration Defeats Surface-Level Defenses in Tool-Using Agents (opens in a new tab)

arXiv cs.CR (AI) ·Md Habibur Rahman, Jaeho Kim ·28 Aug 2026 ·fetched 28 Aug 2026, 19:38 UTC Research agreed2/2

Why readDemonstrates how reframing data exfiltration as standard config fields or integrity signatures achieves 100% bypass rates against LLM prompt injection defenses.

Empirical research on tool-using LLM agents reveals that reframing indirect prompt injection payloads as routine structural elements (such as integrity signatures or trusted host configs) circumvents refusal alignment in models like GPT-4o, increasing successful leak rates from 0% to 100%. The authors show that safety alignment fails because instructions are confused with data, and prove that payload-blind destination allow-lists successfully stop the leak.

Why readNinety days of honeypot telemetry showing real attacker tooling adapted to the internals of LiteLLM, Flowise, Langflow, ChromaDB and Ollama, including RCE against internet-facing MCP servers.

Wiz ran honeypots across self-hosted AI and ML services and recorded sustained, service-specific attack activity rather than generic scanning. Findings group into three patterns, including exploitation of exposed MCP servers for remote code execution and post-exploitation tooling written against AI infrastructure internals to reach credentials and internal systems. Relevant because their cloud telemetry puts self-hosted AI software in 90% of environments, which makes this a mainstream rather than niche attack surface.

Safety Does Not Compose: Non-Decaying Loop State for Autonomous LLM Agents (opens in a new tab)

arXiv cs.CR (AI) ·Chenhao Wu, Haoxuan Jia, Yang Liu, Yingguang Yang ·28 Aug 2026 ·fetched 28 Aug 2026, 18:29 UTC Must read Research agreed3/3

Why readProves that any monitor scoped to a single agent trajectory has a true-positive rate equal to its false-positive rate against an attack whose evidence is split across iterations.

The separation result is the finding: a trajectory-scoped safeguard cannot beat chance when the incriminating evidence never appears inside one window, while a monitor carrying cross-iteration state separates malicious from benign perfectly. The paper also kills the obvious fix, showing a geometrically decaying risk score only imposes a constant cooling-off period that does not grow with the horizon N, so a patient adversary simply waits it out. If you are building guardrails for long-running autonomous agents, this says your safety state must persist across trajectories and must not decay.

MLTracer: Syscall-Based Malicious Model Detection and Labeling, with Static-Scanner Evasion Taxonomy (opens in a new tab)

Binarly (firmware) ·28 Aug 2026 ·fetched 28 Aug 2026, 17:28 UTC Research agreed3/3

Why readDynamic syscall tracing of Hugging Face model files catches malicious models that the platform's static scanners miss, with a taxonomy of the 21 evasion techniques behind those misses.

Binarly ran large-scale dynamic analysis of model files hosted on Hugging Face and compared results against the scanners deployed on the platform. The gap between the two resolves into 21 categorised static-scanner evasion techniques, most of them variations on serialisation tricks already documented in prior work, which is the point: pattern matching on model files stays a step behind. Anyone gating model ingestion on a static scan should assume that gate is porous and add runtime observation.

Beyond F1: Evaluating Coverage and Failure Recovery in AI Model Security Scanners (opens in a new tab)

Why readBenchmarks ModelScan, ModelAudit and Fickling on 170 Pickle and PyTorch artifacts and shows coverage, not precision, is where these scanners fail: ModelScan returned a definitive verdict for only 49.6% of families.

Using a controlled corpus of 170 artifacts across 145 specimen families (135 with binary ground truth, 10 intentionally malformed), the authors separate coverage, analysis completion, definitive decisions, non-security findings and unsupported outcomes rather than reporting F1 alone. ModelAudit reached a definitive security decision for all 135 labelled families, Fickling for 110 (81.5%), and ModelScan for 67 (49.6%); ModelScan was perfect on precision and recall conditional on deciding at all, which is exactly how an F1-only evaluation hides the gap. Fickling found no unique true positives beyond the other two, so the practical conclusion is that a single scanner leaves half the artifacts unjudged and the silent N/A is the risk.

Perturbation Probing: A New Diagnostic for the Fragility of LLM Safety (opens in a new tab)

Unit 42 ·Tony Li, Hongliang Liu and Yuhao Wu ·28 Aug 2026 ·fetched 28 Aug 2026, 23:42 UTC Research agreed3/3

Why readA cheap probing method that locates which parts of an aligned model actually carry RLHF safety behaviour, and finds it is thinner than assumed.

Following their logit-gap steering work on bypassing alignment, Unit 42 asks where alignment physically lives in the network and presents perturbation probing to identify the specific components carrying RLHF-learned refusal behaviour, cheaply enough to run against every model an enterprise deploys. The framing question for defenders is whether safety is a thick perimeter or a thin layer of paint, and the result argues for the latter. If you are evaluating open-weight models for internal deployment, this is a measurement you can apply rather than a claim you have to take on trust.

Low-ASR Backdoors: Exploiting Attack Success Rate Reduction and Attacker-Defender Asymmetry (opens in a new tab)

arXiv cs.CR (all) ·Arham Riaz, Ting Yu ·28 Aug 2026 ·fetched 28 Aug 2026, 17:52 UTC Research agreed3/3

Why readShows attack success rate is an attacker-tunable dial, not a property of a backdoor, and that deliberately suppressing it defeats state-of-the-art backdoor defenses.

Existing backdoor defenses assume a successful backdoor shows a high ASR; the authors present a reverse-training framework that weakens the trigger-target association enough to drive ASR down while preserving the backdoor behaviour and clean-input accuracy. Across multiple datasets, attack families and architectures, current defenses fail consistently under these low-ASR conditions. The result is a structural attacker-defender asymmetry that anyone evaluating model supply-chain defenses should factor into their test criteria.

SPA: Securing Persistent LLM Agents Across Queries with Plan-First Information-Flow Control (opens in a new tab)

arXiv cs.CR (AI) ·Dylan Girrens, Guangjing Wang ·28 Aug 2026 ·fetched 28 Aug 2026, 17:52 UTC Research agreed3/3

Why readA plan-first architecture that applies dual-lattice information-flow control across planning, execution and cross-query state so untrusted tool output cannot steer later queries.

SPA invokes the planner once per query to emit a complete plan in a declarative DSL, then tracks confidentiality and integrity labels over both explicit data flows and control dependencies during execution. Execution results are stored as labeled artifacts and only semantic metadata is surfaced to the planner later, so persistent state does not re-expose attacker payloads. Evaluation runs on AgentDojo plus AgentDojo-MQ, a multi-query extension the authors built to measure secure state reuse, which is the more interesting contribution for anyone building persistent agents.

Research shows how an attacker can leverage DNS rebinding through a victim's browser session to interact with an unauthenticated local Ollama model server under Nvidia NemoClaw. Tracked as CVE-2026-65105, the flaw permits modification of the model's chat template to inject malicious instructions into system prompts. The injected prompt modification persists across future user sessions, bypassing standard guardrails.

Why readA benchmark, Cautious Bench, that measures how often agent guardrails refuse authorized actions because the request merely sounds alarming.

The authors treat guardrail over-safety as the construct to measure rather than a side effect, and build a benchmark where each sample is codesigned with an explicit authorization policy so the safe or unsafe label is a mechanical consequence of that policy rather than an annotator's judgement. A build-time gate re-derives every example to certify it. For anyone shipping an agent behind an action-approval layer, this gives a way to quantify the refusals that block deployment instead of arguing about them anecdotally.
