Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Dependency Vulnerability: The nginx base image was outdated and contained known vulnerabilities; upgrading to a patched version is critical to avoid exploitation of the serving layer.
Cross-Origin Data Leakage: Dead code sent modified CML data to a parent iframe via postMessage, which could leak sensitive data across origins if the parent was untrusted.
