Advanced Contact Form 7 – Compact DB Security & Risk Analysis

This plugin exhibits a concerningly weak security posture due to several critical misconfigurations and the absence of fundamental security checks. The static analysis reveals a significant attack surface with four AJAX handlers, all of which lack authentication checks, exposing them to potential unauthorized access and malicious actions. Furthermore, the presence of the `unserialize` function, coupled with raw SQL queries that are not prepared, presents a high risk of remote code execution and SQL injection vulnerabilities. The extremely low percentage of properly escaped output further exacerbates these risks, as user-supplied data can be directly injected into the application without proper sanitization, leading to cross-site scripting (XSS) attacks.

While the plugin has no recorded vulnerability history, this absence should not be interpreted as a sign of robust security. Instead, it might indicate a lack of rigorous security auditing or a relatively small user base that has not yet attracted widespread vulnerability research. The lack of any recorded CVEs is a positive signal, but it is overshadowed by the immediate and severe risks identified within the code itself. The plugin's reliance on insecure coding practices makes it a prime target for attackers, despite its clean vulnerability history.
