****** cos-html-cache ****** Security & Risk Analysis

The static analysis of cos-html-cache v2.7.4 reveals a mixed security posture. While the plugin boasts a clean vulnerability history with no known CVEs and a seemingly small attack surface in terms of entry points (AJAX, REST API, shortcodes, cron events), the code signals raise significant concerns. Specifically, 100% of its SQL queries are not using prepared statements, and similarly, 100% of its outputs are not properly escaped. This, combined with 5 unsanitized path taint flows identified, indicates a high potential for SQL injection and cross-site scripting (XSS) vulnerabilities, despite the absence of direct indications of these in the vulnerability history. The lack of nonce and capability checks on file operations and potentially other sensitive functions further exacerbates these risks, as there's no built-in protection against unauthorized actions or privilege escalation.
