CB Contact Form Security & Risk Analysis

The "cb-contact-form" plugin version 1.1 exhibits a mixed security posture. On the positive side, it demonstrates good practices by avoiding dangerous functions, utilizing prepared statements exclusively for SQL queries, and having no recorded vulnerabilities or CVEs. This suggests a generally stable and secure codebase in terms of common attack vectors like SQL injection. However, significant concerns arise from its attack surface, particularly the presence of two AJAX handlers that lack authentication checks. This leaves the plugin vulnerable to unauthorized execution of its backend functionalities, potentially allowing attackers to perform actions as if they were authenticated users.

The static analysis reveals a limited but crucial weakness in output escaping, with only 23% of outputs being properly escaped. This opens the door to potential Cross-Site Scripting (XSS) vulnerabilities, where malicious scripts could be injected into the plugin's output and executed in a user's browser. While there are no reported vulnerabilities or CVEs, the lack of auth checks on AJAX handlers and the low output escaping rate represent substantial risks that could be exploited. The plugin's strengths lie in its SQL handling and lack of historical vulnerabilities, but these are overshadowed by immediate, exploitable weaknesses in its entry points and output sanitization.
