PHP2Shell is the public exploit for CVE-2026-109618 (corrupted internal state at the memory limit, allowing hijack during cleanup) and CVE-2026-109619 (double free used to leak memory and defeat ASLR). Orca ran the GitHub tool unchanged against an unpatched PHP server and got command execution. It then built its own exploit with AI from the patch, which worked on PHP 8.4.26 and WordPress. Fixed in 8.2.35, 8.3.36, 8.4.27 and 8.5.12.

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.

Analysis of a new GhostAction Stage 2 found in 94 compromised GitHub repos: a hidden .vscode/tasks.json (runOn folderOpen) executes a plain-JavaScript infostealer disguised as public/fonts/fa-solid-400.woff2. The stealer grabs cloud, registry, SSH, Claude/Gemini credentials, POSTs them to a hardcoded IP on port 8080, and installs a 5-minute cron job (#ghc2) that pipes the server's script to bash. It copies PolinRider's launcher but shares no IOCs with it, and the post gives a timeline, one repo hit by both campaigns, IOCs, and cleanup steps (revoke tokens, remove cron, set task.allowAutomaticTasks off).

Huntress analyzes an October incident where an admin searching Bing for a WatchGuard VPN download landed on watchguard-vpn[.]net, a lookalike site whose popup.js harvests Server/Login/Password, deliberately rejects the first submission to get a second set, and posts to watchguard-ssl[.]online. Unlike earlier iterations (Secplicity, Microsoft Storm-2561), the final payload is the genuine, validly signed WatchGuard installer from the official CDN, so no malware is present for endpoint tools to flag. Covers infrastructure timeline, thin VirusTotal detections, and defender guidance (MFA, monitoring VPN logins from hosting ASNs, blocking domains, publishing official download links).

VulnCheck reproduces and root-causes CVE-2026-76504, an exploited zero-day authentication bypass in Cisco SD-WAN vManage. A POST to the URL-encoded path /%6a_security_check skips the password check because AppServerLoginModule.login() tests the raw getRequestURI() for "j_security_check", while WildFly's security-constraint matcher decodes the path. Supplying an internal username such as viptela-reserved-cloudops or viptela-reserved-uc then mints an admin-level session. Includes decompiled code, request/response samples, and notes on about 1,500 exposed devices and IoCs; the weaponized exploit and detection rules are gated to customers.

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.

ETDI (Enhanced Tool Definition Interface) is a proposed security extension to the Model Context Protocol that adds cryptographically signed and versioned tool definitions, OAuth 2.0 scope-based permissions, Cedar-policy-driven context-aware access control (via engines like Amazon Verified Permissions/OPA), and call-stack verification to stop tool chaining and privilege escalation. It is designed to counter two named MCP threat classes — Tool Poisoning (spoofed/impersonated tool definitions) and Rug Pull attacks (post-approval silent modification of tool behavior) — with concrete pseudocode for signature verification, version/integrity checking, and policy evaluation. The page functions as an implementation guide for MCP client/server builders wanting to harden tool approval and invocation flows.

Huntress documents active exploitation of two AhsayCBS (Ahsay Cloud Backup Server) vulnerabilities being chained together: CVE-2026-105133, an authentication bypass in checkSysPwd, and CVE-2026-105134, an unauthenticated RCE in the Replication Receiver's UpdateReceivers.do endpoint that grants SYSTEM. Attackers use the chain to drop JSP webshells, then deploy a renamed XMRig cryptominer (masquerading as msedge.exe via a modified NSSM binary), a Task-Manager-aware anti-detection PowerShell script, and the vulnerable WinRing0x64.sys kernel driver for hardware-level miner access. Huntress provides IOCs, mitigation guidance (restrict management interface, re-image if compromised) and four Sigma rules targeting each stage of the intrusion chain.

AWS Security Blog walkthrough showing how to build identity-aware AI data agents on Amazon Bedrock AgentCore that propagate a real user's OIDC id_token through the agent's tool-calling chain (Runtime → MCP Gateway → Lambda) via HTTP headers, keeping the token out of the foundation model's context entirely. A Lambda function performs a server-side token exchange using IAM Identity Center Trusted Identity Propagation, assumes a scoped TIP role, and runs the user's Athena query so AWS Lake Formation evaluates the real user's grants, producing per-user row/column access and CloudTrail audit records naming the actual human (onBehalfOf) without rewriting existing governance policies.

CyberForge CVE-of-the-Day #070 on CVE-2026-61500 in Rejetto HFS 3.0.0–3.2.0. The default Koa session-signing key came from Math.random() (CWE-338) and the unauthenticated login handshake leaked outputs of the same generator. That allows recovery of the key, a forged administrator session, and code execution through the legitimate server_code feature. It covers scoring (CVSS 9.8/9.3, EPSS, KEV status), the 3.2.1 fix, a six-step SOC hunting and remediation trail (loginSrp1/2, get_config/set_config pivots, COOKIE_SIGN_KEYS review), and offline jq/Python helpers for container and config metadata.

A rekt.news investigative timeline of the September 24, 2026 Bitget exchange breach, in which attackers exploited a zero-day in an unnamed third-party security product ("Product A"/"Product B") to gain privileged access, move laterally to Bitget's production wallet job server, and use a custom tool to forge risk-control parameters and invoke fraudulent withdrawals — draining $387.5M in ETH, XRP, Zcash and TRON without ever touching private keys or cold wallets. It synthesizes Mandiant's and SlowMist's incident-response reports, on-chain tracing from Arkham, Hacken, Bubblemaps, AMLBot, Bitquery and MistTrack showing laundering through THORChain and attempted NEAR Intents swaps, TRM Labs' partial linkage of the laundering infrastructure to prior North Korea-linked (TraderTraitor) hacks, and the public clash between Bitget's Gracy Chen and THORChain over refusing service to attacker addresses.

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.

agent-wow is an open-source platform that lets LLM agents play World of Warcraft by interacting directly with the AzerothCore private-server network protocol rather than through computer vision or scripted game APIs — the agent itself writes gRPC modules, packet handlers, and even a custom C++ Detour-based pathfinding tool to navigate the world. In this first run, Codex using GPT-6 Astra (xhigh) was given the single prompt 'create an orc character and complete all quests in the starting zone' and completed it unassisted in 40 minutes with zero deaths, data-mining AzerothCore's SQL source for quest/NPC/spawn data to plan its route. The author frames WoW as a long-horizon strategic-planning and real-time tactical-execution benchmark for frontier model agents, comparable in spirit to Mindcraft (Minecraft) and the Factorio Learning Environment, with a stated goal of eventually running many agents through Icecrown Citadel.

A dated research report (Pennyforge, 2026-10-02) that probes the live MCP ecosystem to show it is fragmented across five spec revisions at once: it POSTs initialize/server/discover calls against 186 deduplicated endpoints pulled from the official MCP registry's v0 API, plus 10 popular npm stdio servers spawned via npx. It finds only ~9.7% of responding endpoints speak the new stateless 2026-07-28 wire (which removes Mcp-Session-Id, the initialize handshake, and adds server/discover), that the flagship @modelcontextprotocol/server npm packages still only speak the older 2025-06-18 revision, and documents a "version-echo" methodology pitfall where servers negotiate within a supported range rather than reporting a fixed version — illustrated with a parallel failure mode found in the x402 payment protocol.

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.

GitHub Security Lab describes custom "taskflow" prompts built on their open-source Taskflow Agent to hunt Android app vulnerabilities, reporting 24 findings to date. It walks through two concrete chains: an exported, unprotected MapActivity in OsmAnd that lets any app silently import settings and exfiltrate the user's exact map tile/route coordinates to an attacker server, and a hostname-parsing logic bug plus overly loose cookie-domain check in the Wikipedia Android app that lets a wikipedia:// deeplink load an attacker page (e.g. evil-wikipedia.org) and steal long-lived session cookies for account takeover. The post also candidly notes where LLMs struggle (false positives, mis-estimating severity, missing mitigating factors) versus where they excel (deep knowledge of safe/unsafe API patterns).
