Summary
Pins all GitHub Actions across 6 workflow files to full immutable commit SHAs (21 pins total).
Vulnerability
Using mutable version tags (
@v4,@v6,@v7) means any action author (or attacker who compromises an action repo) can silently push malicious code that runs in CI. The Docker workflows are especially sensitive as they push images to registries.Changes
