Simple Contact Form Plugin for WordPress – WP Easy Contact Security & Risk Analysis

The wp-easy-contact plugin v4.0.3 exhibits a mixed security posture. While it demonstrates good practices in SQL query handling and a high rate of output escaping, significant concerns arise from its attack surface and vulnerability history. The plugin exposes a considerable number of AJAX handlers, with a notable portion (9 out of 29) lacking authentication checks, creating potential entry points for unauthorized actions. Taint analysis reveals two high-severity flows with unsanitized paths, indicating a risk of vulnerabilities if these flows involve sensitive operations or user-controlled input.

The vulnerability history is a significant red flag, with four known CVEs, including one high-severity and three medium-severity issues. The prevalence of Cross-site Scripting and Deserialization of Untrusted Data vulnerabilities in its past suggests a pattern of insecure handling of user input or data serialization. Although no currently unpatched CVEs are listed, the historical pattern and the recent nature of the last vulnerability (August 2025) point to potential ongoing or recurring security weaknesses.

In conclusion, while the plugin has strengths in its SQL practices and output escaping, the unprotected AJAX endpoints, high-severity taint flows, and a history of significant vulnerabilities necessitate caution. The identified risks, particularly the unprotected entry points and past vulnerability types, suggest that attackers could potentially exploit this plugin if proper sanitization and authentication are not rigorously implemented and maintained.
