## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in the Tutor LMS plugin due to improper authorization checks in the Q&A management functionality. Specifically, the 'tutor_qna_create_update' AJAX action validates a user's access based on a provided 'course_id' but performs operations (reading and writing) using a 'question_id' that may belong to a different, unauthorized course. An authenticated attacker with Subscriber-level privileges can exploit this by providing a 'course_id' they have access to alongside a 'question_id' from a private course. This allows the attacker to bypass enrollment restrictions to read private Q&A content and inject unauthorized replies. The issue is fixed in version 4.0.0.
