PressPrimer Quiz plugin lets teachers alter others' quizzes

CVE-2026-10623 · published 4 months ago
Summary

The PressPrimer Quiz – AI Quiz Maker, Exam Builder & Assessment plugin for WordPress does not verify that a user is allowed to change a quiz rule, so a teacher‑level user can modify or delete other teachers’ quiz rules. This could let someone tamper with another teacher’s quiz structure and affect test results. Upgrade the plugin to a version newer than 2.3.0 or apply the vendor’s patch, and restrict teacher‑level permissions to trusted staff.

Original advisory text
PressPrimer Quiz <= 2.3.0 - Insecure Direct Object Reference to Authenticated (Custom+) Arbitrary Modification via 'quiz_id', 'item_id', and 'rule_id' Parameters
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.
