What is CVE-2026-5502?

The Tutor LMS plugin for WordPress is susceptible to unauthorized manipulation of course content due to a flaw in the tutor_update_course_content_order() function. The absence of a proper authorization check allows authenticated users with subscriber-level access or higher to modify course structure without the necessary permissions. This can lead to significant disruptions in course organization, enabling attackers to detach lessons, alter their ordering, and disrupt overall course integrity in the system.
