Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Privilege Escalation: The CI workflow previously granted default write access via GITHUB_TOKEN, allowing a compromised job to modify repository contents or push artifacts. Restricting to read-only contents reduces impact but other permissions (e.g., packages, issues) remain unhardened.
Supply Chain Tampering: Documentation recommended git:// protocol for Gemfile sources, which lacks encryption and authentication, enabling man-in-the-middle tampering of gems. The fix switches to HTTPS, but other docs or scripts may still reference insecure protocols.
