Campfire is a self-hosted tool that runs Claude Code, Codex, Goose, Aider and OpenHands in one tab. Risky actions need permission voting (majority approves, any single deny blocks, 30 second timeout), and session replay traces which file or tool call triggered an action. The post cites Forever Security's finding that Codex followed a planted AGENTS.md instruction over 90% of the time and Claude Code about half the time. It also cites the February Cline release compromise via a poisoned GitHub Actions cache.

Thread on two October 2026 npm compromises: @subql/common 5.8.3 (5 October), published through GitHub Actions OIDC Trusted Publishing after the attacker tampered with the publish workflow, and tensorlake 0.5.144 (8 October), published by the project's own release workflow with valid provenance for about 1 hour 40 minutes. Both ran on install and stole cloud, GitHub, Kubernetes, Vault, SSH and .env credentials; tensorlake also took AI tool and MCP config. Its payload installed a gh-token-monitor service that deletes the home directory if the stolen GitHub token is revoked, so remove it before rotating.

The Pwn Request Reckoning is a Wiz post updating the GitHub Actions pull_request_target threat model for 2026. It covers what GitHub's checkout protections, read-only cache tokens and event policies block, and what still works. Remaining paths: SHA-pinned pre-backport actions/checkout, custom checkout scripts, issue_comment and repository_dispatch triggers, script injection, artifact poisoning, self-hosted runner state and allow-unsafe-pr-checkout. It ends with grep and zizmor audit steps.

farol is a free, MIT-licensed CLI and GitHub Action that runs after an AI code review and gives the human approver a risk verdict (fast track, quick review, careful review) and a 0-100 score for a pull request. It uses the TypeScript type checker, go/types and Python ast to trace which pages, APIs and jobs a change reaches, and it adds diff coverage, security findings and contract breaks. It never executes or sends code.

Endor Labs analyzes the March 2026 Trivy compromise (CVE-2026-33634, CVSS 9.4). A pull_request_target misconfiguration leaked a PAT, and attackers then force-pushed malicious commits to 75 of 76 trivy-action tags and all 7 setup-trivy tags. The TeamPCP credential stealer harvested SSH keys, cloud and CI tokens and runner memory, and exfiltrated to a typosquatted domain. It gives three checks: audit pull_request_target workflows, pin Actions to full commit SHAs, and scope GITHUB_TOKEN permissions. It also notes the limits of SHA pinning.

Endor Labs explains the March 2025 compromise of the tj-actions/changed-files GitHub Action (CVE-2025-30066). Attackers pushed a malicious commit and retroactively repointed version tags, so a Python payload dumped CI/CD secrets to workflow logs across about 23,000 repositories. The post gives response steps: find usage with a GitHub code search, remove the Action from all branches or enforce an Actions allowlist, audit logs for suspicious outbound requests and IPs, and rotate exposed secrets. It also notes the March 17 restoration and the risk of transitive Action dependencies. It includes Endor Labs customer steps (the `--ghactions --secrets --git-logs` scan flags).

Explains the "pwn request" weakness in GitHub Actions. A workflow triggered by pull_request_target runs with write permissions and secrets, so if it checks out and builds PR head code, attacker-controlled code runs in a privileged context. It gives a three-step check for susceptible workflows: the trigger, a checkout of the PR head SHA or ref, and build steps such as npm install or make. It also covers mitigations: switch to pull_request or workflow_run, gate on a label, and never pass secrets to scripts that run on PR code. It notes safe patterns and cites the puppetlabs finding.

Explains how to add AWS Continuum for penetration testing (formerly AWS Security Agent) as a post-deployment gate in CI/CD. Each run is scoped to the commit range since the last passing gate, and it can block promotion to production at a chosen severity threshold. It covers OIDC federation to a least-privilege IAM role, a GitHub Actions worked example, staged report-only rollout, and pitfalls: the baseline advances on passing report-only runs, fail-on-infrastructure-error defaults to fail-open, GitLab pipeline variables can override the committed threshold, and runner credentials need protecting.

Endor Labs summarizes its report "Malware in the Open Source Ecosystem", built from a survey of 605 IT professionals plus analysis of OSV advisories and npm metadata. Over 90% of all OSS malware advisories were filed in 2025, and npm account-takeover advisories rose about 12x (930 of 1,011 ever recorded), often hitting heavily downloaded packages. It also covers the TeamPCP campaign across GitHub Actions, Docker Hub, npm, OpenVSX and PyPI, the axios compromise, and survey findings: only 21% enforce cooldown periods, 51% found malicious packages in 2025, and ownership of the problem is fragmented.

Endor Labs breaks down the May 11, 2026 compromise of 42 @tanstack/* npm packages (84 malicious versions) that carried valid SLSA provenance. The attacker chained a pull_request_target "Pwn Request", GitHub Actions cache poisoning across the fork/base boundary, and OIDC token extraction from Runner.Worker memory, then published directly to npm without stealing any credential. It explains why 2FA, trusted publishing, provenance and branch protection all failed, and lists mitigations: split pull_request_target workflows, treat the cache as untrusted, scope id-token: write to a publish job, pin actions to SHAs, require environment approval, use egress allowlists.

StepSecurity details a new wave of the GhostAction campaign in which attackers used compromised maintainer accounts of Takashi Kitao (pyxel) and Henry Wu (athenadriver, Uber) to push malicious "Security Audit" GitHub Actions workflows to 345 repositories in minutes. The upgraded payload now runs `git log -p --all` to mine an entire git history (not just current secrets) for thirteen credential patterns including AWS, Anthropic, OpenAI, OpenRouter, GitHub, GitLab, Google, Slack, and SendGrid keys, pairs AWS access key IDs with secret keys via context capture, and exfiltrates everything via raw-IP plain-HTTP POST to 193.32.204.199, bypassing DNS-based defenses. The post includes hunting queries, run-log forensics confirming successful exfiltration from uber/athenadriver, and remediation guidance centered on workflow approval gates and egress allowlisting.

Endor Labs documents the compromise of tensorlake@0.5.144, the official npm TypeScript SDK for Tensorlake, which shipped a Shai-Hulud worm payload via a poisoned preinstall hook (node lib/setup.mjs) after the project's main branch was altered and pushed through a legitimate, provenance-signed GitHub Actions release pipeline. The malware harvests npm, GitHub, SSH, cloud (AWS/GCP/Azure), Kubernetes/Docker and Vault credentials, uses an EtherHiding Ethereum wallet as a durable dead-drop to fetch its rotating C2 domain, and republishes itself into other packages the victim controls. The writeup includes affected package versions, file hashes, C2 indicators, and concrete remediation guidance (pin to 0.5.143, rotate credentials, disable install scripts).

StepSecurity recaps a 48-hour (May 18-19, 2026) software supply-chain attack wave that hit every pipeline layer at once: the Nx Console VS Code extension (2.2M installs) stealing tokens from GitHub/npm/AWS/1Password, the trusted GitHub Action actions-cool/issues-helper hijacked via tag replacement, a trojanized Microsoft durabletask PyPI package pulled within a 35-minute discovery window, a self-replicating Shai-Hulud npm worm, and GitHub's own disclosure that ~3,800 internal source repos were exfiltrated. The piece argues traditional SCA/SAST/EDR/CNAPP tooling missed all of it because none monitor CI/CD runner runtime behavior (e.g., attackers reading /proc/pid/mem to extract secrets) or developer-machine IDE extensions, and ties the incidents to StepSecurity's Harden Runner, Dev Machine Guard, Compromised Actions Policy and Secure Registry controls.

StepSecurity's investigation of @subql/common@5.8.3, a malicious npm release in the SubQuery Web3 indexing framework's monorepo, found a heavily obfuscated postinstall/import-time payload (base64+XOR+gzip inside a function constructed via Function()) that spawns a detached worker to steal credentials (.npmrc, .env, AWS, SSH, kubeconfig, Vault, cloud secrets), read GitHub Actions runner memory for CI secrets, inject a camouflaged "Run Copilot" GitHub Actions workflow to exfiltrate repo secrets, and provide a remote shell/PTY over an encrypted channel to ci-artifacts.dev. The release was published via a compromised build pipeline: a workflow modification swapped the real build output for an externally downloaded, unsigned tarball from that same C2 domain immediately before publish, and the authors provide IOCs and remediation steps (credential rotation, host isolation, domain blocking).

Wiz Research examined the source repositories and CI/CD pipelines behind 1,500 popular Helm charts on Artifact Hub (mapping to 814 unique GitHub repos) and found 61 repos (7.5%) with confirmed supply-chain risk, including 20 charts with CI/CD workflow weaknesses and 25 depending on unmaintained/archived upstream projects. Two disclosed findings illustrate the risk classes: KubeView's go.mod referenced a Go module under a GitHub username that didn't exist, making it hijackable by anyone who registered the name, and Meilisearch's Helm chart repo had a GitHub Actions workflow triggered by PR comments that injected the commenter's branch name into a shell command while skipping author-association checks, letting any GitHub user run commands with a bot token that had push access. The post then pivots to promoting WizOS Helm Charts, Wiz's hardened/signed/CVE-scanned chart catalog built to close these gaps.

security-harness is an open-source Claude Code plugin (also packaged for Gemini CLI, Codex and opencode) that orchestrates subagents — sh-recon, sh-hunter, sh-chainer, sh-verifier, sh-reporter — through a static-analysis pipeline covering 15 vulnerability classes (IDOR/BOLA, SQLi, XSS, SSRF, injection, auth, deserialization, path traversal, secrets, CSRF, XXE, open redirect, crypto, race conditions, file upload), producing README/JSON/SARIF/HTML/PDF reports with PoCs, CVSS and CWE/OWASP mappings. It also ships sh-pr-review, a per-PR merge-gate skill that posts inline findings and a commit status scoped only to code the PR itself introduced or aggravated, with caching, dedup via fingerprints, and a scheduled GitHub Action that keeps its per-class knowledge bases fresh by having one AI agent draft updates from allowlisted sources (OWASP, PortSwigger Research, CWE/CAPEC, HackerOne) while a separate adversarial reviewer agent fails-closed against prompt injection before auto-merge.

Two GitHub Actions from the actions-cool maintainer, disabled by GitHub security after May's supply-chain compromise, were reactivated by the maintainer and left accessible for over a week without the malicious release tags being cleaned up. Any workflow still referencing those version tags resumed automatically downloading and executing the Mini Shai-Hulud payload, showing that disabling a compromised action isn't remediation if the poisoned tags survive reactivation.

Agent Threat Rules (ATR) is an open, versioned YAML rule format (ATR-YYYY-NNNNN scheme) for detecting AI-agent runtime threats — prompt injection, tool-poisoning, malicious SKILL.md content, and MCP exchange abuse — evaluated by a reference TypeScript engine (with a Python wrapper) shipped as an npm/pip package, CLI, GitHub Action, and Docker scanner with SARIF output. The project positions itself as "Sigma for agent threats," maps rules to OWASP Agentic/LLM Top 10, MITRE ATLAS, and NIST AI RMF, and publishes an extensive (and unusually self-critical) benchmark suite against corpora like garak, PromptBench, and PromptInject, including documented harness bugs and withdrawn recall figures.

The Hacker News details the "Mini Shai-Hulud" campaign by threat actor TeamPCP, which compromised npm and PyPI packages from TanStack, UiPath, Mistral AI, OpenSearch and Guardrails AI via a chained GitHub Actions attack (pull_request_target abuse, cache poisoning, OIDC token extraction), now tracked as CVE-2026-45321 (CVSS 9.6). The worm mints npm publish tokens directly from stolen OIDC credentials to self-propagate — the first documented case of a worm producing validly SLSA Build Level 3-attested malicious packages — and deploys an obfuscated credential stealer with IDE persistence hooks, a GitHub Actions secret-exfiltration workflow, and a dead-man's-switch that runs "rm -rf" if its rogue npm token is revoked. Over 170 packages and 400+ attacker-controlled repos have been identified across npm and PyPI, with findings credited to Aikido Security, Endor Labs, SafeDep, Socket, StepSecurity, Snyk, Wiz and Microsoft.

git-pkgs is a Go rewrite of a Ruby tool that adds a git subcommand for tracking dependency changes across a repository's history, indexing manifests/lockfiles from 36+ package managers (npm, RubyGems, Cargo, PyPI, Maven, Composer, Go modules, etc.) into a local SQLite database. Beyond history/blame/diff, it offers supply-chain security commands: `vulns` (OSV-based CVE scanning with SARIF output for GitHub code scanning, plus blame/praise/exposure for remediation metrics), `licenses` (with drift detection and CI-friendly exit codes), `deprecated`, `provenance` (trusted-publishing/attestation checks), `integrity` (lockfile hash drift detection), `maintainers`/`health` (via ecosyste.ms metadata), and `sbom` export in CycloneDX/SPDX. It also supports a dependency-aware `bisect` to find when a vulnerability, license change, or capability (e.g. network access) was introduced, and ships GitHub Actions for CI integration.

Socket reports that the actions-cool/issues-helper and actions-cool/maintain-one-comment GitHub Actions, compromised in the May 2026 Mini Shai-Hulud campaign and disabled by GitHub, were re-enabled on September 16, 2026 with their release tags still pointing to the malicious code. Any workflow referencing them by tag (about 15,000 dependents for issues-helper alone) resumed running the Bun-executed obfuscated payload. Workflow run logs show the switch from fast "Repository access blocked" failures to multi-minute successful runs. The post gives remediation: SHA-pin actions, rotate secrets, and hunt for oven-sh/setup-bun and bun run index.js in runner logs. An update says both repos were disabled again on September 25.

StepSecurity documents a supply-chain attack against @memtensor/memos-cloud-openclaw-plugin on npm (versions 0.1.21, 0.1.23, 0.1.25) and MemoryOS 2.0.34 on PyPI, which insert a hidden "sckit" launcher into normal plugin/import lifecycle code (no install scripts) to spawn a platform-specific Go binary that harvests the parent process's environment and the user's AI prompt text. The Go payloads contain regex patterns for AWS, GitHub, GitLab, npm, PyPI, Hugging Face, Vault, Slack, Stripe and SendGrid credentials, target the user's home directory as an inventory root, and beacon to skyleen.fr "front" domains; the PyPI variant additionally hides a conditional build-backend/CI bridge that can steal PYPI_API_TOKEN during publishing and pull a hash-pinned, Ed25519-signed secondary payload via GitHub Actions.

Orca Security details a supply-chain attack on the npm package @dforge-core/dforge-mcp, where a compromised maintainer account modified the GitHub Actions release workflow so any push to main triggered an OIDC-based trusted publish, shipping malicious version 0.2.21 with valid Sigstore provenance. The four-stage GHAPPIER loader activated only when the MCP server launched, deployed a self-deleting remote shell, and per CloudSEK's tracing appeared across 65 repos and 22 accounts; a second payload matched PolinRider, a DPRK-linked campaign using Ethereum transactions for C2. The piece underscores that npm provenance attests build origin, not source integrity, and lists remediation steps since no CVE or advisory yet exists.
