Login & Register Customizer – Popup | Slider | Inline | WooCommerce Security & Risk Analysis

The "easy-login-woocommerce" plugin exhibits a mixed security posture. While it demonstrates good practices like using prepared statements for all SQL queries and a high percentage of properly escaped output, several areas raise concern. The static analysis reveals a notable attack surface with 9 AJAX handlers, of which 4 lack authentication checks, representing a significant potential for unauthorized actions. Furthermore, two flows with unsanitized paths were identified in the taint analysis, although these did not escalate to critical or high severity.

The vulnerability history of this plugin is a major red flag. With 6 known CVEs, including one high and five medium severity vulnerabilities, it indicates a recurring pattern of security weaknesses. The common vulnerability types listed (Missing Authorization, CSRF, XSS) align with the findings from the static analysis, particularly the unprotected AJAX handlers and the potential for unsanitized input. The recency of the last vulnerability (2025-06-19) suggests ongoing security issues. While there are currently no unpatched CVEs, the historical trend necessitates a cautious approach.

In conclusion, the plugin has strengths in its secure SQL handling and output escaping. However, the presence of unprotected AJAX endpoints, unsanitized taint flows, and a history of multiple medium and high severity vulnerabilities, including common types like missing authorization and XSS, significantly increase its risk profile. The plugin is not recommended for use without thorough review and mitigation of identified security concerns, especially the unprotected AJAX endpoints.
