Risk Assessment

The 'post-filters' plugin v1.0.1 exhibits a mixed security posture. While it presents a very small attack surface with no direct entry points like AJAX handlers, REST API routes, or shortcodes, and has a clean vulnerability history with no known CVEs, significant concerns arise from its code analysis. The complete absence of output escaping and the use of raw SQL queries without prepared statements are major red flags. Furthermore, the taint analysis reveals two flows with unsanitized paths, classified as high severity, indicating potential vulnerabilities that could be exploited if an attack vector is found, despite the current lack of one.

Key Concerns

  • SQL queries without prepared statements
  • Output not properly escaped
  • High severity unsanitized taint flows
  • No capability checks
  • No nonce checks
