Recommendation: Monitor — no exploitation signal at the moment.

The Tutor LMS Pro – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.8.3 due to missing validation on a user controlled key when viewing and editing assignments through the tutor_assignment_submit() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view and edit assignment submissions of other students.
