Description
The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to privilege escalation. This is due to the plugin not properly validating a user's identity prior to allowing them to modify their own role via the REST API. The permission check in the update_item_permissions_check() function returns true when a user updates their own account without verifying the role changes. This makes it possible for authenticated attackers, with student-level access and above, to escalate their privileges to administrator by updating their own roles array via a crafted REST API request. Another endpoint intended for instructors also provides an attack vector. Affected version ranges are 3.5.3 - 3.41.2, 4.0.0 - 4.21.3, 5.0.0 - 5.10.0, 6.0.0 - 6.11.0, 7.0.0 - 7.8.7, 8.0.0 - 8.0.7, 9.0.0 - 9.0.7, 9.1.0.
