hunting-cicd-workflow-injection skillA

hunting-cicd-workflow-injection is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt a CI/CD pipeline for attacker-controlled repository data that reaches a privileged execution context, after the trigger and the token scope are resolved. Covers an untrusted event field (an issue or pull-request title, a branch name, a commit message) interpolated directly into a run-step shell command, a pull_request_target or workflow_run job that checks out and builds the pull-request head with secrets in scope, a third-party action pinned to a mutable tag or branch rather than a commit .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/hunting-cicd-workflow-injection@git:20260825.70f8609
Exact content
mdr add unboundcompute/security-agent-skills/hunting-cicd-workflow-injection@sha256:3254ed086ab5de48

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
