EasyCoupon – Create WooCommerce Coupons, BOGO Deals, Auto Apply Coupons, URL Coupons Security & Risk Analysis

The "easycoupon" v1.0.0 plugin exhibits a concerning security posture primarily due to its extensive attack surface exposed without authentication. With 14 AJAX handlers and none of them having authorization checks, any authenticated user on a WordPress site could potentially trigger these functions, leading to unintended actions or information disclosure. While the plugin demonstrates good practices in other areas, such as using prepared statements for all SQL queries and a high percentage of properly escaped output, this lack of access control on AJAX endpoints represents a significant vulnerability. Furthermore, the presence of one flow with unsanitized paths, although not classified as critical or high severity, warrants attention as it indicates potential for unexpected behavior or subtle security issues if data is not handled carefully. The plugin's clean vulnerability history is a positive sign, suggesting a generally well-maintained codebase or a lack of targeted attacks thus far. However, the current static analysis reveals critical gaps in access control that, if exploited, could lead to significant security problems despite the absence of known CVEs.
