Gheist is a campaign tracked by Wiz Research since 15 September 2026 that uses stolen GitHub tokens to push a sync-check workflow on ci-sync-* branches in every reachable repository. The workflow prints base32-encoded secrets into logs, which the tool downloads through the GitHub API and then deletes. Over 13,500 branches from 850+ accounts were recovered. The post covers the two tool variants, a buggy self-hosted runner payload, GitHub's approval hold (which does not cover private repositories), overlaps with other campaigns, hunting queries, IOCs and hardening steps.

Part 2 of an AWS Security Blog series detailing the design of a "steering file" — a persistent instruction set (deployable as a Kiro steering file, Kiro skill, or Claude Code CLAUDE.md) that constrains an LLM performing vulnerability triage. It walks through five configuration sections: requiring structural/dataflow verification before reporting findings, replacing self-reported confidence with a weighted formula based on binary structural signals (e.g., 0.30 weight for confirmed taint flow), mapping infrastructure controls (AWS WAF, IAM) to severity multipliers with a 0.15 floor, incorporating CISA KEV and EPSS threat-intelligence boosts capped at +0.50, and a four-tier priority classification that suppresses low-confidence P3 findings. Validation against a 10-vulnerability test app showed the steered model eliminated fabricated findings and correctly downgraded mitigated vulnerabilities while preserving full severity for a command injection reachable only via authenticated access.

The malicious bw1.js payload shares C2 infrastructure and code (gzip+base64 packed Python memory-scraper, Bun-based runtime, GitHub Actions workflow injector) with the earlier Checkmarx mcpAddon.js attack, but adds new indicators like a lock file, shell-profile persistence, and overt "Shai-Hulud: The Third Coming" / Butlerian Jihad ideological branding, plus a kill switch for Russian-locale systems. It harvests GitHub, AWS, Azure, GCP, npm, SSH, and Claude/MCP credentials and exfiltrates via GitHub commits and npm republishing.

A researcher builds "Vulnerability Spoiler Alert," an open-sourced GitHub Action that uses Claude to continuously scan commits and associated pull requests in monitored repos, flagging likely security patches before a CVE is ever published. The post walks through prompt-tuning iterations (adding PR context, requiring a concrete exploit PoC, using the assistant-prefill trick to force clean JSON output), a timing case study showing an ~2-hour "negative-day" window on the React2Shell patch versus CVE feed publication, and a verified command-injection "never-day" the tool surfaced in vercel/next.js's @next/codemod (execSync with unsanitized shell interpolation), reproduced with a trojanized package.json PoC.

rfxn's technical dissection of CVE-2026-41940 (SessionScribe), an unauthenticated session-forgery bug in cPanel/WHM that lets an attacker forge a root cpsess session via CRLF injection into the password field of an Authorization: Basic request, exploiting the fact that Cpanel::Session::saveSession() skips the CR/LF-stripping filter_sessiondata() sanitization used by the normal login path, combined with an encoder short-circuit when the whostmgrsession cookie's OBHEX suffix is malformed. The writeup reverse-engineers the patched cpsrvd binaries (since cPanel ships no source for this surface) using a custom snapshot/BinDiff workflow, documents an adjacent lower-severity access-log identity-injection issue, and ships an open-source operator toolkit (ModSecurity rule pack, remote probe, on-host IOC scanner, snapshot collector) plus an architectural recommendation to firewall cpsrvd's direct ports behind Apache+mod_security2 proxy endpoints. Credits researcher Sina Kheirkhah of watchTowr Labs for the original PoC.

Sysdig's Threat Research Team details CVE-2026-39987, a critical (CVSS 9.3) pre-authentication RCE in the marimo Python notebook platform's /terminal/ws WebSocket endpoint, which skips the validate_auth() check used elsewhere in the app and grants an unauthenticated interactive PTY shell. Using honeypots deployed within hours of the advisory, TRT observed a single attacker build a working exploit from the advisory text alone (no public PoC existed), run a scripted PoC validation, manually recon the filesystem, and steal .env AWS credentials and search for SSH keys, all in under 3 minutes, with first exploitation just 9h41m after disclosure. The piece argues niche software (20k GitHub stars) is now exploited as fast as major platforms like Langflow, and provides IOCs and hardening recommendations (upgrade to marimo 0.23.0, restrict/disable the terminal endpoint, rotate credentials).

Huntress details a device-code phishing campaign hitting 340+ Microsoft 365 tenants across the US, Canada, Australia, New Zealand, and Germany since February 2026, in which attackers abuse Railway.com's clean-IP PaaS infrastructure to run OAuth device-code token replay at scale, bypassing MFA entirely. The campaign chains vendor URL-rewriter abuse (Cisco, Trend Micro, Mimecast), compromised sites, Cloudflare workers.dev phishing pages, and AI-assisted lure generation, and Huntress has attributed it to the EvilTokens Phishing-as-a-Service platform advertised via Telegram. The post includes IOCs (Railway CIDR ranges), Sentinel KQL hunting queries, and mitigation guidance (block Railway IPs, revoke refresh tokens, restrict device code flow, enable CAE).

CVE-2025-14986 is an identity-binding flaw in Temporal's ExecuteMultiOperation endpoint. The outer request was authorized for one namespace, but inner StartWorkflow operations carried a different namespace that the server used for policy and schema preparation while persisting under the authorized one. The post shows the Go code, two exploits (cross-tenant schema access and policy bypass), and the v1.27 fix, with timeline December 2025 to January 2026.

AppOmni researcher discloses CVE-2025-12420 ("BodySnatcher"), a chain of flaws in ServiceNow's Virtual Agent API and Now Assist AI Agents application that let an unauthenticated attacker impersonate any user with only their email address, bypassing MFA/SSO via a hardcoded, instance-agnostic Message Auth secret and insecure Basic account-linking. By reverse-engineering the protected AIA-Agent Invoker AutoChat topic and its A2A adapter, the attacker can trigger the built-in "Record management" AI agent to create a backdoor admin user entirely through async, supervised-mode agent execution — escalating from zero access to full platform admin. The writeup includes full HTTP PoC payloads and recommends enforcing MFA on account linking, an AI agent approval workflow, and lifecycle de-provisioning of dormant agents.

CVE-2025-64721 is a Sandboxie vulnerability in the SYSTEM service SboxSvc.exe, reachable over the raw ALPC port \RPC Control\SbieSvcPort. The RC4Crypt handler never checks value_len against the message length, giving an out-of-bounds heap read and, via a 32-bit integer overflow (0xFFFFFFF1), a 4GB heap write. The post explains a two-thread vtable-hijack plan to escape the sandbox. It was reported and patched on 12 November 2025.

A Huntress researcher walks through Device Code Phishing, an OAuth 2.0 device authorization grant abuse technique, and shows why it is far more dangerous against Azure/Microsoft 365 than against Google Cloud. In Azure, the attacker controls the requested resource and can use Microsoft's undocumented "Family of Client IDs" (e.g. the Microsoft Authentication Broker client ID) to phish a Primary Refresh Token capable of joining rogue devices, enrolling MFA, and full account takeover; Google's device code implementation restricts the flow to a handful of narrow scopes (GDrive file access, YouTube read-only) and requires a registered/verified OAuth app, neutering the same attack. The piece includes working curl/Python requests for both providers and references prior research by Dirk-jan Mollema, Nestori Syynimaa, and Lina Lau.
