Editorial Analysis
This mirrors the tj-actions/changed-files incident and reinforces that pinning GitHub Actions to mutable tags is a systemic risk; any org using this action may have leaked repository secrets.
Audit CI/CD workflows for codfish/semantic-release-action usage, rotate any exposed secrets, and pin all GitHub Actions to immutable commit SHAs.
A compromised open-source CI/CD component may have exfiltrated repository credentials from any project that used it.
