+ Pin actions to a full length commit SHA is currently the only way to use an action as an immutable release. Pinning to a particular SHA helps mitigate the risk of a bad actor adding a backdoor to the action's repository, as they would need to generate a SHA-1 collision for a valid Git object payload. Ref: https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions + Explicitly set permissions for actions to minimum required. The defaults are (unfortunately) overly permissive: Ref: https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token Signed-off-by: Chris Evich <cevich@redhat.com>
