Vulnerability from github – Published: 2026-02-03 09:30 – Updated: 2026-02-03 09:30

Details

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object References (IDOR) in all versions up to, and including, 3.9.5. This is due to missing object-level authorization checks in the course_list_bulk_action(), bulk_delete_course(), and update_course_status() functions. This makes it possible for authenticated attackers, with Tutor Instructor-level access and above, to modify or delete arbitrary courses they do not own by manipulating course IDs in bulk action requests.

Severity ?

8.1 (High)
