CPT Calender Widget for WordPress Security & Risk Analysis

The static analysis of cpt-calender-widget v1.0.0 reveals a generally good security posture regarding attack surface. There are no identified AJAX handlers, REST API routes, shortcodes, or cron events, meaning there are no direct entry points for attackers to exploit. This lack of exposed functionality is a significant strength. However, the code does contain one instance of the `create_function` which is considered a dangerous function in PHP and can be a vector for code injection if user input is not strictly controlled. Additionally, only 17% of SQL queries utilize prepared statements, leaving a substantial portion vulnerable to SQL injection. The 50% rate of proper output escaping is also a concern, indicating potential for cross-site scripting (XSS) vulnerabilities. The absence of any recorded vulnerabilities in its history is a positive indicator, suggesting the developers have maintained security over time. Despite the clean vulnerability history, the presence of dangerous functions and insecure SQL practices warrants caution. Overall, while the plugin has a minimal attack surface, the identified code-level issues represent potential security risks that need to be addressed.
