Post Grid Master — Post Grids & AJAX Filters Security & Risk Analysis

The "ajax-filter-posts" plugin exhibits a mixed security posture. While the static analysis shows a commendable effort with 80% of SQL queries using prepared statements and 85% of outputs being properly escaped, significant concerns remain. The presence of 7 known CVEs, with one still unpatched and classified as critical, is a major red flag. This history includes severe vulnerability types like XSS, missing authorization, PHP Remote File Inclusion, and Path Traversal, indicating a recurring pattern of insecure input handling and access control issues in past versions. The taint analysis revealing two flows with unsanitized paths, although not reaching critical or high severity in this specific scan, are potential precursors to the types of vulnerabilities seen in its history, especially when combined with past findings of "Improper Control of Filename for Include/Require Statement" and "Path Traversal". The plugin's attack surface, though currently showing no unprotected entry points, has historically been a source of significant risk.
