Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Credential Exposure: The use of custom, high-privilege repository secrets (like GH_TOKEN) in pull request workflows risks exposing powerful credentials to external contributors or untrusted code execution. Transitioning to ephemeral tokens mitigates this high-severity vector.
Privilege Escalation: Default GITHUB_TOKEN permissions in GitHub Actions are often overly permissive (write access by default), enabling malicious actors who compromise a workflow or exploit a runner to escalate privileges within the repository.
