MailBluster for WordPress Security & Risk Analysis

The mailbluster4wp plugin, version 2.2.4, presents a mixed security posture. On the positive side, it demonstrates strong practices regarding SQL queries, utilizing prepared statements exclusively, and does not appear to have a history of known vulnerabilities, which is a significant strength. The absence of dangerous functions and file operations further bolsters its perceived security. However, the plugin has a concerningly high number of unprotected entry points. With 3 out of 4 identified entry points (AJAX handlers) lacking authentication checks, there's a significant risk of unauthorized access and execution of plugin functionalities.
