External Actions not pinned to a commit SHA

Referencing a GitHub Action by a mutable tag (uses: actions/checkout@v4) means the action's code can change without your knowledge. Pinning to a commit SHA (uses: actions/checkout@<sha>) ensures the exact code you reviewed is what runs.

HOW VIBECHECK DETECTS THIS

vibecheck clones your repository and runs Gitleaks, Semgrep, njsscan, and a suite of custom checks targeting patterns common in AI-generated code. This check is part of the Supply Chain category. When a matching pattern is found, Claude triages the finding and produces a plain-English explanation and a concrete fix — no security expertise required.
