QuadMenu – Mega Menu Security & Risk Analysis

Quadmenu v3.3.2 presents a mixed security posture. While the static analysis indicates a relatively clean entry point surface with all AJAX handlers and REST API routes appearing to have authorization checks, and a significant percentage of SQL queries utilizing prepared statements, there are notable concerns. The code signals reveal that only 56% of output is properly escaped, which is a significant weakness that could lead to cross-site scripting (XSS) vulnerabilities if malicious data is ever introduced through unsanitized inputs. Furthermore, the taint analysis shows flows with unsanitized paths, although they are not currently classified as critical or high severity, they represent potential avenues for exploitation.

The vulnerability history is a significant red flag. The plugin has a history of two known CVEs, including one critical vulnerability and one medium, with the most recent one being dated April 2025. While there are no currently unpatched vulnerabilities, the past critical and medium severity issues, particularly Cross-Site Request Forgery (CSRF) and Unrestricted Upload of File with Dangerous Type, indicate a pattern of exploitable flaws. This history suggests that developers may not consistently address security best practices throughout the development lifecycle. In conclusion, while Quadmenu v3.3.2 has some strengths in its access control for entry points and SQL query sanitization, the high percentage of unescaped output, unsanitized taint flows, and a concerning historical pattern of critical and medium vulnerabilities necessitate caution.
