Related Posts by Taxonomy Security & Risk Analysis

The 'related-posts-by-taxonomy' plugin v2.7.8 exhibits a generally good security posture with several strengths, including no identified critical or high severity taint flows, no external HTTP requests, and no file operations. The plugin also has a limited attack surface with all identified entry points featuring authentication checks. However, there are areas for improvement. The static analysis indicates that 33% of SQL queries are not using prepared statements, which can be a potential vector for SQL injection if the inputs are not meticulously sanitized, though no specific taint flows were found in this analysis.

The plugin's vulnerability history shows one known medium severity CVE related to Cross-Site Scripting (XSS). While this vulnerability is currently unpatched according to the data, the last vulnerability was dated in the future (2026-01-15), which might be an anomaly in the provided data. The fact that the only known vulnerability was medium severity and involved XSS suggests that input validation and output escaping might be areas where the plugin could be more robust, as evidenced by only 69% of outputs being properly escaped.

In conclusion, the plugin demonstrates a commitment to security by minimizing its attack surface and implementing some security checks. The lack of critical vulnerabilities or taint flows is a positive sign. However, the presence of non-prepared SQL queries and the historical XSS vulnerability, coupled with a moderate percentage of unescaped output, highlight potential weaknesses that require attention for a more secure implementation.
