The GitHub Advisory Database now includes curated security advisories for vulnerabilities on GitHub Actions. This brings the Advisory Database to ten supported ecosystems, including: Composer, Go, Hex, Maven, npm, NuGet, pip, RubyGems and Rust.
If you have a dependency on any vulnerable GitHub Actions, GitHub will send Dependabot alerts over the coming days.
Ubuntu 22.04 is now generally available on GitHub-hosted runners. To use it now, simply add runs-on: ubuntu-22.04 in your workflow file. Otherwise, our recommendation is to use ubuntu-latest, which currently utilizes Ubuntu 20.04 but will begin running on Ubuntu 22.04 in the near future. This will ensure your workflows are always using a recent OS and removes the need to constantly update workflow files with image versions.
