Summary
Academy LMS for WordPress is affected in all versions up to and including 4.0.3. The delete_lesson_comment AJAX action does not check authorization for the target comment (CWE-862). An authenticated user with custom-level access who instructs at least one course can permanently delete lesson comments and replies from other courses, including administrators' comments.

Description from the CNA
The Academy LMS – AI Course Builder, Quizzes, Certificates & eLearning plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with custom-level access and above, to permanently delete arbitrary Academy lesson comments and their replies authored by any user, including administrators, across courses they do not instruct. This is exploitable by any user registered as an Academy instructor for at least one course, as they can supply their own course_id to pass the instructor check while targeting comments belonging to entirely different courses.
