GitHub Actions Security Tool: Lock Dependency Versions to Prevent Code Tampering

GitHub Actions currently lacks a built-in version locking mechanism, creating security risks. The newly launched gh-actions-lockfile tool addresses this pain point by pinning all actions (including transitive dependencies) to exact commit SHAs and integrity hashes, effectively preventing malicious code tampering. This tool supports generating and verifying lockfiles, visualizing dependency trees, and can be used as either a GitHub Action or CLI tool. By locking version tags, developers can ensure workflow stability and security, avoiding unexpected code changes caused by version tag retargeting. This tool offers significant practical value for developers who rely on GitHub Actions for automated deployment.
