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.

Executive Summary

This vulnerability exists in the LifterLMS WordPress plugin, where it improperly validates a user's identity before allowing role modifications via the REST API. Specifically, the permission check in the update_item_permissions_check() function incorrectly returns true when a user updates their own account without verifying changes to their role. This flaw allows authenticated users with student-level access or higher to escalate their privileges to administrator by crafting a REST API request that modifies their own roles array.

Impact Analysis

An attacker who exploits this vulnerability can escalate their privileges from a low-level user (such as a student) to an administrator. This means they could gain full control over the WordPress site using the LifterLMS plugin, potentially allowing them to modify content, access sensitive data, change settings, or install malicious code, severely compromising the security and integrity of the site.
