DBHub, a database MCP server, had a read-only mode bypass in its SQL check. The check treated every `--` as a comment, but MySQL only starts a comment when whitespace follows it. A hidden write statement could therefore still run, and a prompt injection could trigger it. Fixed in version 0.22.6. Replies say enforcement belongs in database grants and that parser tests need to be dialect-specific.

Polymarket's international site was hit on 29 October 2026 when a page-speed monitoring script served from DebugBear's CDN was replaced with a drainer. It hijacked logged-in sessions for about an hour and took $2.7M from 726 wallets via Polymarket's relayer. Scott Helme of Report URI says the CSP allowlisted every domain used and that hash pinning would have blocked the swapped file. Polymarket is repaying $3.9M, and this is its second vendor-script compromise since June.

Reply on X explaining a Bytecode Alliance advisory for Wasmtime's Cranelift compiler backend. A large or crafted Wasm function that generates enough SSA values overflows Cranelift's value-index representation, which packed indices into 24-bit fields. The fix widens them to 32 bits. The issue is not AArch64-specific, and the advisory names no required optimisation level. Guard pages do not reliably stop the resulting miscompilation and type confusion, so a sandbox escape can arise at compile time.

CVE-2026-106173 is an unauthenticated arbitrary file write in the FortiSIEM phQueryMaster gRPC service on tcp/27918, advised by Fortinet on 13 October 2026. The SendQueryResult handler concatenates an attacker-controlled query-id into a path, and a null byte in the header removes the server-added filename suffix. Overwriting /opt/charting/redishb.sh, run every 60 seconds by cron, gives root-level code execution. IOCs are file timestamps.

ToFu is a tool-aware fuzzing framework that derives semantic security checks for LLM tools (mainly MCP servers) from their metadata and a corpus of 74 CWE-guided sanitizers. It generates schema-valid Atheris harnesses, uses runtime tracers and outcome oracles to catch bugs that don't crash, and uses an LLM only to map sanitizers and seed inputs, never as the judge. It also describes a "Repeat-After-Me" attack, in which the LLM is told to repeat attacker-written text that the orchestrator then dispatches as a tool call. It was reproduced on LangGraph, MAF, ADK, AutoGen, Strands and CrewAI. On 273 MCP servers it reports 253 verified bugs across 343 tools in 118 repositories, including path traversal, log injection, exfiltration and command bypass.

On multi handle cleanup, server data lands in the freed memory and can overwrite a function pointer, giving remote code execution. Daniel Stenberg lists why exploitation is hard (~135KB upload, ~23-byte payload, allocation-dependent) and says Luna Tong at Anthropic found it with an OSS Scanner.

Rapid7 analysis of CVE-2026-97229, a CVSS 10.0 integer overflow (CWE-190) in the Onigmo regex compiler used by GitLab CE/EE's CI/CD regex handling. A crafted regex in a .gitlab-ci.yml passes validation as US-ASCII, then is recompiled for a UTF-8 repository path, producing invalid instructions that give code execution as the git user. Rapid7 reproduced it on GitLab CE 19.4.1 with ASLR (patched in 19.4.2); despite the vendor's "unauthenticated" rating, the attacker needs to commit a malicious config to a public project, which self-registration allows. No in-the-wild exploitation is confirmed, and Rapid7 recommends urgent upgrades.

Rootshell Security Bulletin #22 (Aug 1998) reports an ICQ authentication flaw found by a Linux ICQ clone developer. The Mirabilis server stores 8-character passwords, and sending a password of 9 or more characters (e.g. "123456789") overflows the buffer and logs the client in as any UIN not already online. This gives full account takeover, including receiving offline messages. It is not spoofing, and it works with unofficial clients such as zicq, since the official client enforces the length limit client-side.

Compares static SCA (manifest/source scanning at build time) with dynamic SCA (runtime instrumentation). Static scans are complete but noisy and miss dependencies absent from manifests, for example in Python. Dynamic scans are relevant but incomplete, add agent overhead and surface findings late. It argues eBPF improves deployability of dynamic SCA but not its coverage limit. A worked example with a library of N vulnerable functions illustrates the difference. The author, Endor Labs, advocates static analysis of source code plus reachability analysis to filter findings by whether vulnerable code is actually called.

VulnCheck's exploit development team analyzes CVE-2026-76504, a critical zero-day authentication bypass in Cisco Catalyst SD-WAN Manager (vManage), reproduced to the point of a weaponized exploit. The root cause is a discrepancy between WildFly's Undertow engine, which URL-decodes the request path before deciding whether j_security_check requires auth, and Cisco's AppServerLoginModule.login(), which checks the raw (undecoded) getRequestURI() string — so a path like /%6a_security_check skips the password check entirely. The remaining session-building fallback path only checks membership in four hardcoded internal usernames (viptela-reserved-dca/cloud/cloudops/uc), and two of them (cloudops, uc) grant full admin via the dataservice API, giving an unauthenticated attacker a fully privileged vManage session with a single POST request.

Hackers-Arise walkthrough of EvilWAF, an open-source MITM proxy and standalone WAF vulnerability scanner that evades modern behavior-based WAFs by rotating TCP/TLS fingerprints (JA3/JA4) rather than altering attack payloads. It covers proxying sqlmap traffic through EvilWAF, its auto-hunt feature for discovering and routing directly to the real origin IP behind a WAF, and its scan-only mode that probes ten WAF defense layers (rule engine, rate limiting, HTTP method handling, TLS settings). The piece also discusses why Cloudflare's ML-based behavioral fingerprinting resists many of these bypass techniques.

AWS Security Blog's second post in a series on building an "AI vulnerability harness" explains the configuration (steering file) that stops an AI model from hallucinating vulnerabilities and inflating severity during security code review. It details five configuration sections — structural verification of findings, an evidence-based confidence formula (weighting confirmed taint flow at 0.30), infrastructure-aware severity multipliers for controls like AWS WAF and IAM, CISA KEV/EPSS threat-intel boosting, and a four-tier priority classification — and reports validation numbers (e.g., unsteered models fabricated code paths in ~30% of findings; steered confidence of HIGH without structural confirmation was only 34% exploitable vs 89% with confirmed taint). The steering file is shipped as a Kiro steering file, a Kiro skill, and a CLAUDE.md for Claude Code, with full source in a linked GitHub repo.

AWS Security Blog describes a three-layer AI-assisted pipeline for triaging vulnerability scanner findings: Layer 1 cross-checks multiple scanners (e.g., Semgrep, CodeQL) for agreement, Layer 2 verifies a scanner's claimed data-flow path against the code's actual abstract syntax tree to catch hallucinated findings, and Layer 3 cross-references infrastructure-as-code (CloudFormation/Terraform) to weigh whether existing controls like AWS WAF rules actually mitigate the exploit path. It argues progressive, escalating-evidence filtering plus mandatory structural verification of LLM claims before human review is what turns noisy scanner output into a short, trustworthy, prioritized list, and lays out an adoption order (indexing, then multi-scanner triage, then AI hypothesis generation, then infra context, then live PoC verification).

Microsoft Security's FORGE Lab shares results and lessons from four months of AI-agent-driven vulnerability research: 140 Windows CVEs (52 in September 2026's release), 155 internally validated reports across 23 open-source projects, and the first patch merged into the Linux kernel via the Linux Foundation's Akrites coordinated-disclosure initiative. Using their multi-model agentic scanning harness MDASH and GPT-5.5-based validation agents, the team measured automated PoC generation at an average $3.61/21.5 minutes per confirmed crash and local privilege-escalation AEG at $8.56/25.4 minutes, and argues the real bottleneck has shifted from finding bugs to validating and remediating them at matching speed. Specific disclosed CVEs include curl's CVE-2026-9545 and CVE-2026-13608, Node.js's CVE-2026-56848, and Linux kernel's CVE-2026-64563.

This arXiv paper examines why current LLM-based automated vulnerability-patching benchmarks overstate model performance, identifying pitfalls at the agent level (prompting/tooling inflating success without improving patch quality), framework level (permission errors, infra bugs, timeout handling silently skewing scores), and dataset level (single PoC tests failing to verify root-cause fixes). The authors curate 112 historical bugs across 84 open-source C/C++, Go, and Rust projects, each annotated with PoC tests, regression tests, and developer-intent tests, and show that while PoC pass rates look high, developer-test pass rates stay low and barely improve with newer models. They provide guidelines for more rigorous, reproducible evaluation of LLM patching systems.

The flaw is in ExecutionAction.run in mindsearch/agent/graph.py, which passes the planner LLM's output directly to Python's exec() — if the model's reply lacks a code fence, the entire response is executed, and a crafted query to the /solve endpoint can get the model to emit attacker-controlled code that runs as root inside the shipped Docker container (which binds 0.0.0.0:8002). The author notes prompt filtering cannot fix this since the attacker only needs the model's output to contain code, and recommends running any agent that executes model-written code in a network-isolated, non-root sandbox kept off public ports.

HyBind is an intraprocedural Python static-analysis framework that traces cryptographic component secrets through code to determine whether post-quantum/traditional (PQ/T) hybrid key-derivation and signature-verification logic actually requires both algorithms to succeed, rather than silently accepting a result from only one. It uses registered API contracts and function-return/execution-effect checks to distinguish real AND-logic hybrids from presence-based heuristics that wrongly treat joint and single-algorithm contributions as equivalent. The authors validate it on 50 controlled fixtures and 33 programs (15 using native ML-KEM/X25519 and ML-DSA/Ed25519 APIs), showing relaxed checks can misclassify traditional-only results as hybrid.

This IACR ePrint paper presents a Linux runtime cryptographic discovery system built on eBPF user-space probes that detects both classical and post-quantum (ML-KEM) cryptographic operations as they execute, complementing static binary/SBOM analysis with dynamic observation. It uses "randomness anchoring" — correlating observed key-generation/encapsulation randomness with subsequent crypto API calls in the same process — to raise detection confidence without adding false positives, reporting perfect precision/recall on classical and ML-KEM workloads, median detection latency of 28 μs, and 14–18% overhead on key-generation-bound workloads. A nine-application case study (drawn from/paired with QED datasets) compares static vs. runtime views and shows how eBPF probe coverage limits what can be observed, relevant to building a runtime cryptographic bill of materials for PQC migration compliance.

An IACR eprint paper evaluating all 13-cubed ways to assign 13 post-quantum/traditional signature parameter sets across the Root, Intermediate and Leaf roles of a TLS 1.3 certificate chain, holding the algorithm set fixed and varying only placement. Across 286 three-algorithm groups, median max/min ratios reach 2.085x for TLS handshake latency, 4.310x for certificate body size and 4.551x for path-validation cost purely from role order, with Leaf placement mattering far more than Root/Intermediate swaps. It also shows that looking only at Certificate-message size can misrank candidates such as ML-DSA-65 versus SLH-DSA-SHAKE-192s once the Leaf signature in CertificateVerify and full authentication-path cost are included, arguing PQC certificate-chain design must account for role-specific cost under real network/load conditions.

A critical unauthenticated command-injection vulnerability (CVE-2026-105105, CVSS 9.8) was disclosed in NASA AMMOS AIT-Core, software used for spacecraft command and telemetry operations. The flaw stems from AIT-Core's ZeroMQ message bus binding to 0.0.0.0 on TCP port 5559 by default with no authentication, letting any network-reachable attacker publish onto internal topics such as __commands__, potentially injecting spacecraft command data, reading/forging telemetry, and disrupting the command-and-telemetry bus. Affects AIT-Core <= 3.1.1, fixed in 3.1.2 by binding ZeroMQ XSUB/XPUB interfaces to 127.0.0.1; no known in-the-wild exploitation.

A forum writeup on ethresear.ch describing a "predictions-first" testing methodology for verification logic, applied against the author's own repository and against a live third-party MCP server (nsgoods Workbench, which offers offline signature verification over the x402 payment catalogue). Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure. The author ships a companion tool, exactzk-verification-guards, which captures both a passing and an actually-reproduced failing run as regression evidence rather than a fabricated example.

Snyk explains why AI coding agents reliably ship broken object-level authorization (BOLA/IDOR) bugs: the ownership rule that would prevent them (e.g. "invoices belong to organizations") lives in the product's data model and team knowledge, not in the prompt or surrounding code, so the agent produces code that is correct for the stated task but lets any authenticated user access other tenants' objects. The piece maps the flaw to CWE-639/862/863, contrasts it with pattern-matchable classes like SSRF and path traversal that SAST handles well, and lays out five concrete team actions (endpoint inventory, documented ownership rules, explicit authz review questions, per-resource cross-tenant tests, and periodic deep contextual analysis), while pitching Snyk's "application-context graph" and Evo Agentic AppSec as the tool for the pattern-less gap.

Horizon3.ai discloses CVE-2026-61500, a session-forgery vulnerability in Rejetto HTTP File Server (HFS) 3.x found using Anthropic's Mythos model. HFS seeds Koa's keygrip session-signing key with V8's insecure, invertible Math.random() PRNG and separately leaks raw Math.random() outputs through an unauthenticated login endpoint; by sampling a dozen leaked outputs and feeding them to the Z3 SMT solver, an attacker can recover the xorshift128+ internal state, step it backwards to the process-start signing key, and forge an admin session cookie that leads to remote code execution via HFS's built-in admin JavaScript execution feature. The piece walks through the full exploit chain and argues that Mythos independently chained the crypto weakness and the leak, built the Z3-based key-recovery solver, and produced a working PoC without additional prompting.

Evaluating seven frontier models (including Qwen3-Coder-Next and GPT-5.5) at file/block/line granularity, the authors find every model explores most of the gold evidence but reports only a fraction of it: Qwen3-Coder-Next views 86.3% of annotated lines but cites just 12.9%, while GPT-5.5 views 73% and reports 36%.

The Hacker News independently confirmed the vulnerable handler shipped only in two PyPI pre-releases, 0.4.3.dev1 and 0.4.3.dev2, not the stable 0.4.2.2 release, and it remains unpatched on PyPI even though maintainers hardened GitHub main at commit b047730 after Microsoft's MSRC report. The piece frames this as a generalizable pattern for agent frameworks, localhost checks treated as auth, unauthenticated local control planes, and agents that browse untrusted content, also seen in the ChatGPhish case and Microsoft's Semantic Kernel RCE research.

CVE-2026-65695 is a path traversal vulnerability (CWE-22, CVSS 4.0 7.6 HIGH) in Office-Word-MCP-Server through version 1.1.11, an MCP server that exposes Word document manipulation tools to LLM agents. Attackers who can influence the filename argument can supply absolute paths or ../ sequences to document open/save operations, bypassing the check_file_writeable and ensure_docx_extension helpers (which do no base-directory confinement or realpath validation) to read or overwrite arbitrary .docx files outside the intended working directory.

CVE-2026-65056 describes a server-side request forgery in the mcp-webresearch MCP server (npm package @mzxrai/mcp-webresearch, v0.1.7), scoring CVSS 4.0 8.3 HIGH. The visit_page tool only validates URL protocol and does not filter private, loopback, link-local, or cloud metadata IP ranges, so an attacker who controls the LLM-supplied URL argument (e.g. via prompt injection) can steer the server's Playwright browser to internal endpoints like cloud instance metadata services and exfiltrate sensitive internal content, including credentials, back into the model context.

CVE-2026-55544 describes an authorization bypass (IDOR/BOLA) in NextCRM CRM version 0.12.1, where MCP campaign tool handlers accept user-generated Bearer API tokens but query and mutate campaigns purely by object ID, ignoring the authenticated user's ownership scope. A low-privileged user with a valid MCP token can enumerate, read, modify, delete, or trigger/pause campaigns belonging to other users. Fixed in NextCRM 0.12.2.

CVE-2026-52869 describes a session-hijacking flaw in the MCP Python SDK (PyPI package mcp) prior to version 1.27.2: the SSE and stateful Streamable HTTP transports (mcp.server.sse.SseServerTransport and mcp.server.streamable_http_manager.StreamableHTTPSessionManager) route requests to existing sessions using only the session_id query parameter or Mcp-Session-Id header, without checking that the requesting principal matches the session's original authenticated bearer-token client. This lets a different authenticated client that learns or guesses a valid session ID inject JSON-RPC messages into another user's MCP session. CVSS 3.1 base score 7.1 (High); fixed in mcp 1.27.2.

n8n's AI Agents module did not enforce the "Allowed HTTP Request Domains" restriction on credentials. A member-level user with use-only access to a shared credential could point an MCP tool at an attacker-controlled URL and run the agent, so the credential secret was sent to an external server. It only affects instances with the agents module enabled via N8N_ENABLED_MODULES and a domain-restricted credential shared with a member. It is fixed in 2.28.1 and 2.27.4, and the advisory rates it High (CVSS v4 7.1).

A GitHub Security Advisory (GHSA-5p9g-j988-pcwv) documents a session poisoning flaw in the Ruby MCP SDK's Streamable/SSE HTTP transport: the server never validates that a POST to /messages/{session_id} actually belongs to the caller, so an attacker who obtains a victim's session ID (e.g. via logs or network sniffing) can silently execute tool calls whose responses are delivered into the victim's own SSE stream. The advisory includes a working PoC (attacker/legitimate client scripts against the SDK's example streamable_http_server.rb), notes that csharp-sdk and go-sdk correctly bind sessions to user identity while ruby-sdk does not, and distinguishes the bug from the related "Stream Replacement" advisory (GHSA-qvqr-5cv7-wh35), which disconnects rather than poisons the victim's stream.

GHSA advisory for jovancoding/network-ai disclosing that its MCP HTTP transport (bin/mcp-server.ts, lib/mcp-transport-sse.ts) accepts JSON-RPC tools/call requests with zero authentication, session, or origin checks, and binds to 0.0.0.0 by default. The PoC shows an unauthenticated attacker can enumerate 22 registered tools and invoke privileged ones - config_get/config_set to read and mutate live orchestrator configuration, agent_list/agent_spawn/agent_stop, token_create/token_revoke, budget_set_ceiling, and blackboard_write/delete - with curl requests against a local Docker deployment. Remediation recommended enforcing bearer-token auth in _handlePost() before dispatch, defaulting to 127.0.0.1 binding, and gating state-mutating tools behind authorization checks.

GHSA-9hgc-g3w5-67cm details a DNS TOCTOU race in IBM mcp-context-forge's /admin/gateways/test endpoint: validate_gateway_test_url() resolves and vets a hostname against private/cloud-metadata IP ranges, but the actual request is made with httpx (via ResilientHttpClient), which independently re-resolves DNS at connection time with no IP pinning. An attacker with gateways.read permission can exploit DNS rebinding (short-TTL record flipping from a public IP to 169.254.169.254) to bypass SSRF protections and reach cloud instance metadata, exfiltrating IAM credentials where IMDSv1 is enabled. The advisory notes the codebase already acknowledges the gap in two comments and a tracked TODO (ICACF-15), and recommends pinning the validated IP into the connection.

GHSA advisory detailing three bypasses in Flowise's Custom MCP Server security controls (validateCommandFlags and validateArgsForLocalFileAccess in packages/components/nodes/tools/MCP/core.ts) that combine to achieve remote code execution: an unblocked `docker build` subcommand that pulls and runs a remote Dockerfile, a missing `--yes` long-flag alias on the npx blocklist (only `-y` was blocked) enabling arbitrary npm package execution, and a Unix absolute-path regex that fails to catch double-leading-slash paths (`//root/...`), allowing `node` to execute an uploaded local file. Any authenticated Flowise user (or an API key with chatflow view/update rights) can chain these to fully compromise the host via a prediction API call.

A GitHub PoC chaining two n8n CVEs into unauthenticated RCE: CVE-2026-21858 abuses a Content-Type confusion in the Form Trigger/Respond-to-Webhook nodes to read arbitrary files (e.g. /proc/self/environ, the SQLite database, and the config file), from which the attacker derives the JWT secret from n8n's encryptionKey and forges an admin session cookie. That admin access is then used to create a workflow exploiting CVE-2025-68613, an expression-injection sandbox bypass (`this.process.mainModule.require`) that yields command execution, all demonstrated with a working Python exploit script and Docker lab against n8n 1.65.0. It notes the exploit was developed independently of a prior Cyera/Dor Attias write-up on a related n8n chain and details the specific vulnerable workflow pattern (file-upload form + binary Respond node) required for exploitation.

Belgian CCB advisory on CVE-2026-48710 ("BadHost", CVSS 6.5), an authentication bypass in Starlette versions before 1.0.1. The Host header was not validated when request.url was rebuilt, so request.url.path could differ from the routed path. Middleware and endpoints that enforce access control on request.url could therefore be bypassed. The flaw affects FastAPI, LiteLLM, vLLM, MCP servers and other Python LLM infrastructure, and may expose stored third-party credentials.

HoF-Bench is a benchmark of 95 real, publicly disclosed CVEs originally found by AISLE's LLM-based vulnerability analyzer (280+ CVEs across 78 projects including OpenSSL, curl, and GnuTLS), repackaged into eight repositories pinned at vulnerable commits. Analyzers get source/target-file scope but no CVE ID, description, fix, or expected mechanism, and a detector-blinded frontier-model judge only credits findings that match the same code path, root cause, attack condition, and impact. Testing ten non-frontier backbones (open-weight 21B-284B and proprietary "flash"-tier models) in a fixed multi-pass scaffold, a minimal analyzer rediscovers up to 68% of the CVEs, with misses concentrated in C infrastructure code — showing small/cheap models can approximate frontier-level vulnerability discovery on known bug classes.

This paper evaluates authentication code generated by five prominent AI coding assistants, combining static code analysis and dynamic penetration testing mapped against NIST SP 800-63B guidelines. It tests four prompting strategies (Basic, Secure, NIST-Based, and iterative Reprompting) and finds that basic and generically "secure" prompts consistently miss critical protections like brute-force resistance, session management, and password handling, while even a single-shot NIST-context prompt is structurally inadequate — only an iterative self-auditing reprompting loop achieves defense-in-depth. The authors argue enterprises must shift from single-shot prompt engineering to continuous, standards-driven verification pipelines for AI-generated auth code.

This paper introduces CWE-Trace, a benchmark of 834 manually curated Linux kernel vulnerability samples spanning 74 CWEs with a strict temporal split to eliminate training data leakage. Evaluating eight vanilla LLMs including DeepSeek-R1 and fifteen LoRA fine tuned variants, the authors find contamination gives no real advantage and that fine tuning only shifts output calibration rather than underlying security reasoning, with the best model barely beating chance and CWE ranking accuracy staying very low. Two new diagnostic metrics are introduced to expose this calibration without comprehension failure mode.

OpenAnt is an open-source (Apache 2.0) vulnerability discovery system that combines static program analysis with LLM reasoning in a three-stage pipeline: decomposing codebases into reachability-filtered analysis units (cutting analysis surface up to 97%), running adversarial verification where the model simulates a constrained attacker to judge exploitability, and validating candidates via dynamic testing in disposable sandboxed containers. Evaluated against large real-world projects including OpenSSL, WordPress, and Flowise, it reportedly surfaced previously unknown vulnerabilities while cutting false positives and keeping analysis cost manageable, positioning closed-loop LLM+exploit-validation pipelines as a practical path to scalable automated security analysis.

A Snyk blog post arguing that vulnerability backlogs traditionally managed as "accepted technical debt" have become genuine attack surface, because AI-accelerated code generation has pushed vulnerability inflow to roughly six new findings per one remediated, unauthored AI-written code removes the "ask the author" triage shortcut, and cheap automated reconnaissance lets attackers walk large backlogs an analyst never would. It illustrates how individually-low-severity findings (an IDOR leaking an internal object ID, a verbose error confirming valid IDs, and an outdated deserialization library) can chain into an authenticated RCE path invisible to severity-based sorting, and argues better prioritization only reorders a backlog rather than shrinking it. It closes with four metrics programs should measure (90-day inflow vs. closure, age of risk-accepted findings, share of human-authored merges, and security-fix merge rate) before promoting Snyk's Evo product.

This fork adds containerized (Docker-based) exploit validation, measured-impact PoCs (rows leaked, amplification factor, etc.), and portability across agent harnesses (Claude Code, Codex, Grok, etc.) via environment-contract prompt files, plus an unattended operator (vulnhunter-run) and batch-scanning/benchmark harness tested against OWASP NodeGoat, Juice Shop, and WebGoat.

CVE-2026-93485 (CVSS 7.1) is a stored XSS-to-RCE chain in WordPress Core's wpautop() function (wp-includes/formatting.php), where a mismatch between comment sanitization at save time and HTML reformatting at display time lets an unauthenticated attacker inject live event handlers via a crafted comment. When a logged-in administrator views the page, the script executes and installs a malicious plugin containing a web shell, achieving full RCE. It affects WordPress Core 4.7 through 7.1.0 (essentially all installs, including block themes since Twenty Twenty-Two), and is fixed in 7.1.1 with backports down to 4.7.36; no public PoC or in-the-wild exploitation was reported at disclosure time.

A Docker-based exploitation lab for CVE-2026-26980, an unauthenticated blind SQL injection in Ghost CMS's Content API (versions before 6.19.1). The bug lives in slug-filter-order.js, where slug values from the array-notation filter syntax (filter=slug:['value']) are interpolated unsanitized into an ORDER BY CASE statement, letting NQL's single-quote-wrapped literals smuggle raw SQL past input validation; since MySQL treats || as OR and empty strings as falsy, attackers get a clean boolean oracle to extract data (e.g. admin email/password hash) from any Ghost site using only the publicly embedded Content API key.

Because the tool is only invoked via LLM decision, the researcher bypassed the model's safety guardrails by injecting fabricated function_call/function_call_output entries into the /v1/responses conversation history, tricking the LLM via in-context learning into emitting a real malicious tool call with a traversal payload. This illustrates how LLM safety training can be the sole runtime control gating dangerous tool arguments, and how that control can be defeated with conversation history injection.

watchTowr's rapid-reaction analysis of CVE-2026-85706, a critical (CVSS 10.0) unauthenticated path traversal in GitLab CE/EE's repository commits API, patched in versions 19.3.2, 19.2.6, and 19.1.8. The flaw lets an unauthenticated attacker read arbitrary files (configs, secrets) from self-managed GitLab servers via crafted requests to /api/v4/projects/{id}/repository/commits/ with a file.path parameter; watchTowr reproduced the bug and reports honeypot probes indicating attackers have already reverse-engineered it ahead of mass exploitation.

watchTowr's rapid-reaction analysis of CVE-2026-85706, a critical (CVSS 10.0) unauthenticated path traversal vulnerability in the GitLab CE/EE repository commits API, patched in versions 19.3.2, 19.2.6, and 19.1.8. The flaw allows an unauthenticated attacker to read arbitrary server-side files via the commits API due to improper path confinement and missing auth enforcement; watchTowr's honeypot network was already observing exploitation probes at time of publication. The post includes hunting guidance (searching logs for POST requests to /api/v4/projects/{id}/repository/commits/ containing file.path parameters) and patching priorities for self-managed instances.

Wiz Research documents active in-the-wild exploitation of three JFrog Artifactory vulnerabilities: CVE-2026-42018 (exposes an internal anonymous-user JWT via POST /access/api/v1/aws/token/), CVE-2026-42016 (token scope validation flaw allowing that JWT to be escalated to admin via POST /access/api/v1/tokens), and CVE-2026-82329 (unauthenticated admin access via POST /access/api/v1/registry/join, added to CISA KEV). Attackers chained the first two to create persistent admin accounts, deploy malicious Groovy plugins for RCE, and drop Rust-based C2 backdoors, while CVE-2026-82329 was exploited independently for configuration exfiltration, cluster join-key theft, and credential/SSH-key persistence. The post includes exact request sequences, detection signatures, affected/fixed version ranges, and remediation guidance.

A public PoC repo for CVE-2026-42533, a pre-auth heap buffer overflow in nginx's two-pass string evaluation engine that occurs when a regex-based map directive using numbered captures ($1, $2) clobbers the shared r->captures state used by a regex location, causing a LEN/VALUE size mismatch. The overflow can corrupt an adjacent ngx_pool_cleanup_t structure to hijack a function pointer for RCE, or under-write to leak heap/libc pointers defeating ASLR; the repo ships exploit.py/leak.py/overflow.py plus a Docker test environment demonstrated at 10/10 reliability on Ubuntu 24.04 against nginx 0.9.6-1.30.3/1.31.2. It also documents the exact vulnerable config pattern, a config scanner link, and the fix (named captures or upgrade to nginx 1.30.4+/1.31.3+).

Aikido argues the widely-shared a16z/Epoch AI chart showing critical/high CVEs jumping from under 100/month to over 600/month since spring 2026 reflects AI accelerating vulnerability discovery, not a real spike in danger — since CISA's KEV count has stayed flat. It details how NIST's NVD, overwhelmed by volume, let its scoring backlog balloon from 13,000 to 27,000 CVEs in 18 months and pivoted to only prioritizing federal/critical/KEV-listed CVEs, while Verizon's 2026 DBIR found only 26% of confirmed actively-exploited KEV vulnerabilities were fully remediated in 2025 (down from 38%) with median patch time rising to 43 days. It illustrates the point with StyleSmuggler, an unauthenticated RCE hitting Adobe Commerce and Magento Open Source that had no CVE or vendor advisory, which Aikido Intel flagged and Aikido Libraries auto-patched more than 24 hours before Adobe's own hotfix.

A Snyk blog post arguing that preventing new vulnerabilities in agent-generated code is architecturally solved, using Laurie Voss's nested "loop" model (execution/task/product/system/oversight) to map four control types — in-context guidance, deterministic scanning inside the agent loop (Snyk's Trusted Output Assurance), LLM-based semantic analysis for authz/business-logic flaws like IDOR, and adversarial pentesting/red-teaming (Snyk's Continuous Offensive Security) — to the points in the SDLC where each is cost-effective. It cites Snyk VulnBench JS 1.0 data showing nearly half of LLM-found vulnerabilities appear in only one of five identical review runs, illustrating why single-pass LLM scanning needs repetition to be trusted, and closes by distinguishing solved "prevention" from unsolved "remediation" of existing vulnerability backlogs.

AWS Security announces Deception Benchmark, a 14,822-sample dataset across 16 languages and 70+ CWE categories designed to test whether AI models can tell exploitable vulnerabilities apart from code that merely looks risky but is safely mitigated (e.g., parameterized SQL queries, Kubernetes Network Policies blocking SSRF). Evaluating 12 frontier models from five providers, the team found none achieved both false-positive and false-negative rates below 10%, with precision clustering in the mid-50s — essentially coin-flip accuracy when flagging vulnerable vs. safe code. The dataset, evaluation harness, and whitepaper are released on GitHub, with roughly a third of samples held out unscored to resist benchmark gaming.

LL-Verifier is a research framework that uses LLMs to autonomously translate natural-language protocol descriptions and security goals into formal logic models (built on the Maude language) and security properties, which are then exhaustively checked by a logic model checker to uncover application logic flaws. The authors applied it to 27 access control protocols from widely used IoT devices and found multiple previously unknown, vendor-specific logic vulnerabilities with real security/privacy impact, demonstrating a scalable alternative to manual expert-driven logic flaw analysis.

Wiz researchers chain three LiteLLM flaws into a full pre-auth-to-cloud-compromise path: an MCP endpoint authentication bypass (CVE-2026-59822) that grants a session with any garbage Bearer token, a custom-code-guardrail sandbox bypass leading to root RCE (CVE-2026-59821) via exec() on unsanitized admin-submitted Python, and a config-endpoint authorization gap (CVE-2026-35029). They also show pass-through endpoints can be pointed at the AWS IMDS to steal IAM credentials, bypassing IMDSv2 via header-prefix forwarding. A scan of ~3,074 internet-facing instances found 9.6% accepting the default sk-1234 master key or no auth at all, and CVE-2026-59822 is now in CISA's KEV catalog with observed in-the-wild exploitation.

Trail of Bits found a bug in Lean's String.Pos.Raw.extract (affecting all stable versions up to 4.33.1, fixed in 4.34.0-rc1) where the logical definition and the compiled native code disagree on the result of extracting a slice at an out-of-bounds position, letting an attacker manufacture a contradiction (empty string = non-empty string) that "proves" any theorem, including a fake formalization of Fermat's Last Theorem. The exploit only works when a proof relies on the native_decide axiom, which extends trust to the compiler rather than the kernel; the researchers found the issue while using GPT-5.6 to build a code-review skill, and Lean maintainers hargoniX and Rob23oba shipped fixes within hours to days of disclosure. The post is a reminder that machine-checked proofs are only as trustworthy as the evaluator/compiler paths behind axioms like native_decide, and points to work like lean4lean and alternative kernels as mitigations.

Endor Labs ran Claude Fable 5.1 (on Claude Code) and OpenAI's GPT-6 Astra (on Codex) through its Agent Security League benchmark, which tasks agents with fixing historically-vulnerable code without being told a vulnerability exists, then checks both functional tests (FuncPass) and hidden upstream security tests (SecPass). Fable 5.1 topped the board at 87.2% FuncPass but only 37.4% SecPass, and of patches that passed all functional tests, 57% still left the flaw exploitable — illustrated with CVE-2023-31146 in the Vyper compiler, where swapping a store/copy order re-introduces an out-of-bounds write invisible to functional tests. The post also breaks down token/turn cost economics (cache-read-heavy spend, timeouts billed in full) and argues that cheaper, better-scoring models actually worsen the human-review cost structure since reviewers can't tell secure passes from insecure ones without checking every patch.

GhostJS is an open-source Burp Suite extension by TrinetLayer that passively scans JavaScript, HTML, and JSON responses flowing through Burp for hardcoded secrets (AWS/GCP/Azure keys, Stripe/PayPal/GitHub tokens, JWTs, private keys, etc.) and hidden API endpoints, surfacing findings in a dedicated tab with severity, confidence scoring, remediation guidance, and Markdown export. It also actively fetches referenced <script> bundles using the tester's live session cookies and applies a false-positive filter to suppress doc-sample and placeholder keys, making it a practical recon aid during authorized web app pentests and bug bounty work.

pashov/skills is a set of Claude Code "skills" built by Pashov Audit Group that turn an AI coding agent into a Solidity security auditor: an "x-ray" command for quick codebase reconnaissance, a "solidity auditor" mode that runs multiple different agent personas over a codebase (or specified files) looking for vulnerabilities, and a "fizz" command for additional automated checks. It packages smart-contract audit tradecraft into reusable AI agent skills rather than a standalone scanner, letting developers or auditors invoke deep, multi-pass Solidity review directly inside their coding assistant.
