MasterStudy LMS WordPress Plugin vulnerabilities

The MasterStudy LMS WordPress Plugin before version 3.7.50 does not perform per-object ownership or capability checks when updating orders through its REST API, allowing users with the Instructor role to modify any order on the site, granting free course enrolment, revoking other users' paid enrolments, and tampering with order notes.

The MasterStudy LMS WordPress plugin before version 3.7.46 does not perform an authorization check before returning per-student course enrollment and progress data. This allows unauthenticated attackers to disclose the enrolled courses and learning progress of any registered user.

The MasterStudy LMS WordPress plugin before version 3.7.46 does not properly verify authorization when retrieving order line-item data. This allows any authenticated user, including Subscribers, to read other instructors' course sales records by supplying another user's identifier.
