Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Supply Chain: Third-party actions were unpinned, allowing a malicious commit or compromised tag to inject code into CI and exfiltrate secrets or tamper with artifacts.
Credential Leak: actions/checkout persisted credentials, which could be leaked into build artifacts or logs, exposing the GITHUB_TOKEN or other secrets.
Privilege Escalation: Default workflow permissions granted the GITHUB_TOKEN broad write access, enabling a compromised step to escalate and modify repository contents or other workflows.
