Description

The Tutor LMS WordPress plugin before 3.9.13 does not perform any authorization or post-target validation before creating a comment in one of its handlers, and stores the comment pre-approved, allowing authenticated users with subscriber-level access and above to post auto-approved comments containing arbitrary HTML and links on any content across the site, bypassing the comment moderation queue.
