Risk Assessment

Based on the provided static analysis, the 'content-cleaner' plugin version 1.0 demonstrates an excellent security posture. The absence of any detected attack surface points, such as AJAX handlers, REST API routes, shortcodes, or cron events, significantly limits the potential for malicious interaction. Furthermore, the code signals reveal a strong adherence to secure coding practices, with no dangerous functions, all SQL queries using prepared statements, and 100% properly escaped output.
