Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HUNT-CICD — CI/CD Pipeline Security
## Crown Jewel Targets
Jenkins `/script` console reachable = immediate RCE. A GitHub Actions `pull_request_target` (or `workflow_run`) workflow that checks out the **PR head ref** and references untrusted `${{ github.event.* }}` in a shell `run:` = "Pwnrequest" → secret exfil from a fork PR with zero approval.
**Highest-value findings:**
- **Jenkins Script Console** — Groovy execution → full RCE → dump the credential store
- **Jenkins CLI file read (CVE-2024-23897)** — pre-auth `@/etc/passwd` arg expansion → read `secret.key`/`credentials.xml` → forge admin → RCE
- **GitHub Actions `pull_request_target` injection (Pwnrequest)** — fork PR controls `${{ }}` inside a privileged shell step → exfil `GITHUB_TOKEN` (often `contents:write`) and org secrets
- **Self-hosted runner poisoning** — non-ephemeral runner on a public repo executes a fork PR's build → attacker code runs on the runner host → persistence + secret theft
- **OIDC trust-policy abuse** — over-broad `sub` claim wildcard in an AWS IAM role trust policy → any workflow in the org assumes a privileged cloud role

How to install
mdr add novaestellar/novahaku/hunt-cicd@sha256:612b1072ce2c5559The line at the top of this page pins the label git:20260922.d3f0e63, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
