Nginx Cache Controller Security & Risk Analysis

The "nginx-champuru" v3.3.4 plugin exhibits a strong security posture based on the provided static analysis and vulnerability history. The absence of known CVEs and a clean vulnerability history, with no recorded vulnerabilities, suggests a mature and well-maintained codebase. The static analysis further reinforces this, revealing a minimal attack surface with all identified entry points having authorization checks. The code also demonstrates good practices like a high percentage of prepared statements for SQL queries and a majority of properly escaped output. Nonce and capability checks are also implemented, further hardening the plugin against common attack vectors.
