What the vulnerability does
01Description
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course enrollment in all versions up to, and including, 3.9.3. This is due to a missing capability check and purchasability validation in the `course_enrollment()` AJAX handler. This makes it possible for authenticated attackers, with subscriber level access and above, to enroll themselves in any course without going through the proper purchase flow.
Explanation of Vulnerability in Simple Terms
02Summary
Tutor LMS versions up to 3.9.3 lack proper authorization checks, allowing authenticated users to modify content they should not have access to. An attacker with a low-privilege account can change data belonging to other users or courses. The vulnerability requires login but no special interaction from victims. Update to a version newer than 3.9.3 to resolve this issue.
