zizmor is a static analysis tool for GitHub Actions.

It can find many common security issues in typical GitHub Actions CI/CD setups, including:

  • Template injection vulnerabilities, leading to attacker-controlled code execution
  • Accidental credential persistence and leakage
  • Excessive permission scopes and credential grants to runners
  • Impostor commits and confusable git references
  • ...and much more!
