Details

The PressPrimer Quiz – AI Quiz Maker, Exam Builder & LMS Assessment Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.3.0 via the 'rule_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with custom-level access and above, to modify or delete quiz rules belonging to other teachers, resulting in unauthorized tampering of another user's quiz structure.

Severity
