Paid course content disclosure via mismatched enrollment check

Published Aug 6, 2026 · Updated Aug 6, 2026

Authorization bypass in Themeum Tutor LMS before 3.9.14 allows remote authenticated users to view paid content from courses they have not joined. Protected lesson, quiz, and assignment requests accept a course query parameter and test enrollment against that course rather than the requested content's owning course. Subscriber access and enrollment in any course are sufficient; the result is read-only disclosure of paid course materials.
