  • audit_workflow

    Audits a GitHub Actions workflow YAML file for the real, documented vulnerability classes that have caused actual incidents: script injection via untrusted event-context expressions (issue/PR titles, comments) interpolated directly into `run:` shell steps; third-party actions pinned to a mutable tag/branch instead of a commit SHA (the tj-actions/changed-files supply-chain attack pattern); a missing or overly-broad `permissions:` block; and pull_request_target combined with checking out the PR's own head commit (lets a fork's PR run arbitrary code with your secrets). Parses real YAML structure,…

  • check_expression_injection

    Focused check: scans a single shell command string (as it would appear in a `run:` step) for GitHub Actions expression syntax (${{ ... }}) referencing event-context fields that carry attacker-controlled text, and explains the env-variable fix. Useful for checking a snippet without a full workflow file.
