This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
