What is CVE-2026-1375?

The Tutor LMS plugin for WordPress is susceptible to Insecure Direct Object References (IDOR) due to a lack of proper authorization checks. Specifically, functions such as course_list_bulk_action(), bulk_delete_course(), and update_course_status() allow authenticated users with Tutor Instructor permissions to alter or remove courses that they do not own. By manipulating course IDs in bulk action requests, attackers can exploit this vulnerability, compromising the integrity of course management within the platform.
