CVE-2026-10630: CWE-639 Authorization Bypass Through User-Controlled Key in hookandhook WP Courses LMS – Online Courses Builder, eLearning Courses, Courses Solution, Education Courses
The WP Courses LMS WordPress plugin up to version 3.2.29 contains an authorization bypass vulnerability via the 'resultID' parameter. Authenticated users with custom-level access or higher can enumerate incrementing resultID values to read other users' quiz answers and scores. The vulnerability arises from missing validation on this user-controlled key and insufficient access control, as the only check is a nonce exposed to all logged-in users.
AI Analysis
Technical Summary
CVE-2026-10630 is an insecure direct object reference vulnerability (CWE-639) in the WP Courses LMS plugin for WordPress, affecting all versions up to and including 3.2.29. The flaw allows authenticated users with custom-level access or above to bypass authorization controls by manipulating the 'resultID' parameter in the wpcq_get_quiz_result AJAX action. The endpoint relies solely on a nonce check (wpc_nonce) that is accessible to all logged-in users, providing no effective authorization barrier. This enables attackers to enumerate and access quiz results belonging to other users.
Potential Impact
An attacker with authenticated access at custom-level or higher can read quiz answers and scores of other users, potentially exposing sensitive educational data. There is no impact on integrity or availability reported. The confidentiality of user quiz results is compromised.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict user roles and permissions to limit access to authenticated users with custom-level access. Monitor for updates from the vendor hookandhook regarding an official fix.
