Security Fixes
Harden Runner
Harden-Runner is an open-source security agent for the GitHub-hosted runner to prevent software supply chain attacks. It prevents exfiltration of credentials, detects tampering of source code during build, and enables running jobs without sudo access.
Least Privileged GitHub Actions Token Permissions
The GITHUB_TOKEN is an automatically generated secret to make authenticated calls to the GitHub API. GitHub recommends setting minimum token permissions for the GITHUB_TOKEN.
Pinned Dependencies
Pinning GitHub Actions to specific versions or commit SHAs ensures that your workflows remain consistent and secure.
Unpinned actions can lead to unexpected changes or vulnerabilities caused by upstream updates.
Keeping your actions up to date with Dependabot
With Dependabot version updates, when Dependabot identifies an outdated dependency, it raises a pull request to update the manifest to the latest version of the dependency. This is recommended by GitHub as well as The Open Source Security Foundation (OpenSSF).
Runner Label Replacement
Runner labels define where GitHub Actions workflows execute. Replacing runner labels allows you to migrate workflows from one runner environment to another, such as moving from GitHub-hosted runners to self-hosted runners or vice versa.
This control automatically updates runner labels across your workflows based on the configured label mapping, ensuring consistent runner usage across your repository.
