CVE-2026-11988: CWE-639 Authorization Bypass Through User-Controlled Key in thimpress LearnPress – WordPress LMS Plugin for Create and Sell Online Courses
The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.9.1 via the 'userId' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the course enrollment progress and completion data belonging to any instructor or administrator account on the site. This IDOR does not apply when the target user is a regular subscriber, as the guard correctly blocks cross-subscriber access; exploitation is limited to cases where the victim user holds the LP_TEACHER_ROLE or administrator role.
AI Analysis
Technical Summary
CVE-2026-11988 is an authorization bypass vulnerability (CWE-639) in the LearnPress WordPress LMS plugin affecting all versions up to and including 4.3.9.1. The vulnerability is due to insufficient validation of the 'userId' parameter, which is user-controlled. Authenticated attackers with subscriber or higher privileges can exploit this to access course progress and completion data of users with LP_TEACHER_ROLE or administrator roles. The vulnerability does not permit access to data of regular subscribers, as the plugin correctly restricts cross-subscriber data access. No official remediation or patch information is currently available.
Potential Impact
An attacker with subscriber-level or higher access can view sensitive course enrollment progress and completion information of instructors and administrators. This exposure compromises confidentiality of user data related to course progress but does not affect data integrity or availability. The vulnerability does not allow access to other subscribers' data, limiting the scope to privileged user roles.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict subscriber-level user access where possible and monitor for suspicious activity related to course data access. Avoid granting unnecessary elevated privileges to users. Follow vendor updates for official patches or mitigations.
