AI Analysis
Technical Summary
CVE-2026-88847 is a missing authorization vulnerability (CWE-862) in the MasterStudy LMS WordPress Plugin versions prior to 3.7.50. The plugin fails to check whether a user is enrolled in a course before permitting the recording of lesson completions. As a result, any authenticated user can manipulate course progress data for courses they do not have access to, potentially undermining course integrity and user progress tracking.
Potential Impact
An attacker with any authenticated user account can falsely record progress in courses they are not enrolled in. This could lead to inaccurate course completion records and potentially unauthorized access to course-related features or benefits tied to progress tracking. There is no indication of remote code execution or data disclosure beyond the course progress manipulation.
Mitigation Recommendations
Upgrade the MasterStudy LMS WordPress Plugin to version 3.7.50 or later, where this authorization check vulnerability has been fixed. No other mitigation is required if the plugin is updated.
