Ultimate Classified Listings – Classifieds, Directory & Marketplace Security & Risk Analysis

The ultimate-classified-listings plugin v1.7 presents a moderate to high security risk. While it shows some positive security practices, such as a high percentage of properly escaped outputs and the use of prepared statements for SQL queries, significant concerns arise from its attack surface and vulnerability history. A substantial portion of AJAX handlers lack proper authorization checks, creating a large entry point for potential unauthorized actions. Taint analysis, although not revealing critical or high severity issues in this specific scan, identified flows with unsanitized paths, which could be exacerbated by a lack of authorization.

The plugin's historical vulnerability data is a major red flag. With 9 known CVEs, including 3 currently unpatched high-severity vulnerabilities, and common types like Missing Authorization, CSRF, PHP Remote File Inclusion, and XSS, the plugin has a clear pattern of exploitable weaknesses. The recent vulnerability in September 2025 further indicates ongoing security issues. This history suggests a recurring inability to consistently secure the plugin against common web vulnerabilities.

In conclusion, the plugin has a concerning security posture. The combination of an unprotected attack surface and a history of significant vulnerabilities, particularly unpatched high-severity ones, outweighs its positive aspects. Users of this plugin should be aware of the elevated risk and consider alternatives or ensure strict patching and monitoring practices are in place.
