Void Contact Form 7 Widget For Elementor Page Builder Security & Risk Analysis

The "cf7-widget-elementor" plugin v2.4.2 exhibits a mixed security posture. While it demonstrates good practices such as using prepared statements for all SQL queries and generally implementing capability checks, there are significant concerns regarding its attack surface and output escaping.

The static analysis reveals one unprotected AJAX handler, which represents a direct entry point for unauthenticated attackers. The high percentage of unescaped output (60%) is particularly worrying, as it increases the likelihood of Cross-Site Scripting (XSS) vulnerabilities being exploitable, even if not explicitly detected in the limited taint analysis. The presence of the `unserialize` function, although not directly linked to a detected vulnerability in this analysis, is a known risk factor that requires careful handling of user-supplied data.

The vulnerability history shows a pattern of past issues including XSS, missing authorization, and CSRF, with the most recent in August 2024. While there are currently no unpatched CVEs, the recurring nature of these vulnerability types suggests potential recurring weaknesses in input validation and authorization logic. The plugin's strengths lie in its SQL handling and lack of raw SQL queries, but the identified unprotected entry point and prevalent output escaping issues, coupled with past vulnerability trends, necessitate a cautious approach.
