GrL'Ca MailGuard Security & Risk Analysis

The grlca-mailguard plugin version 1.1.0 exhibits a strong security posture based on the provided static analysis. A significant strength is the complete absence of dangerous functions, file operations, and external HTTP requests, which are common vectors for exploitation. Furthermore, all SQL queries are secured with prepared statements, and all output is properly escaped, mitigating risks of SQL injection and cross-site scripting (XSS) respectively. The presence of nonce and capability checks on its AJAX handlers indicates a good understanding of WordPress security best practices for controlling access to sensitive functionalities. The lack of any recorded vulnerabilities in its history further supports this positive assessment.
