DescriptionThe LearnDash LMS plugin for WordPress is vulnerable to authorization bypass in versions 4.25.0 - 5.1.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to enroll arbitrary users in paid courses without payment verification, bypassing the entire payment system and gaining unauthorized access to premium educational content.
