Post of the Day Security & Risk Analysis

The 'post-of-the-day' v1.0 plugin demonstrates some positive security practices, such as no recorded vulnerabilities and a small attack surface. The static analysis indicates a low number of entry points, with no unprotected AJAX handlers or REST API routes. The absence of dangerous functions, file operations, and external HTTP requests is also a positive sign. However, the analysis also reveals significant areas of concern. Notably, only 44% of SQL queries use prepared statements, leaving a substantial portion vulnerable to SQL injection. Furthermore, a very low percentage (27%) of output is properly escaped, increasing the risk of cross-site scripting (XSS) vulnerabilities. The plugin also lacks capability checks on its shortcode, meaning any user, regardless of their role, could potentially trigger its functionality. This lack of proper authorization for the shortcode, combined with the SQL and output escaping issues, presents a notable security risk.
