Risk Assessment

The 'advance-custom-html' plugin v2.0.4 exhibits a strong security posture based on the provided static analysis. All identified entry points (two AJAX handlers) appear to have authentication checks, and there are no REST API routes, shortcodes, or cron events that could be exploited. The code demonstrates good practices with 100% of SQL queries using prepared statements and all output being properly escaped. Furthermore, there are no identified dangerous functions, file operations, or external HTTP requests, and a nonce check is present. The absence of any recorded vulnerabilities in its history is also a positive indicator.

Key Concerns

  • No explicit capability checks on entry points
  • Bundled Freemius library may pose a risk
