Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Privilege Escalation: Workflow permissions defaulting to writable can allow a compromised or malicious step to push code, modify releases, or exfiltrate secrets, escalating from CI execution to repository compromise.
Security Hardening: Read-only permissions reduce the blast radius of any workflow compromise, but were applied inconsistently across workflows, leaving other workflow files potentially still writable.
Denial of Service: Without timeout limits, CI jobs can hang indefinitely, consuming runner resources and blocking the pipeline, leading to availability degradation.
