Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Privilege Escalation: Default GitHub Actions token permissions can allow compromised workflows to escalate privileges and modify repository contents or access secrets. The fix restricted permissions to read-only, but new workflows or modifications could reintroduce excessive scopes.

Dependency Vulnerability: The nokogiri dependency had a known memory corruption/execution vulnerability (CVE-2017-9050). Using an unpatched version could expose the tool to remote code execution when processing untrusted HTML. The fix bumped the constraint to >=1.8.1, but future downgrades or loose constraints could reintroduce the risk.
