CVE-2025-12426Network attack vector

Quiz answer disclosure via publicly exposed nonce

Published Nov 19, 2025 · Updated Nov 19, 2025

Sensitive information exposure in AYS Pro Quiz Maker 6.7.0.80 and earlier allows remote attackers to read quiz answers via AJAX. The ays_quiz_check_answer action treats a nonce as authorization even though quiz_maker_ajax_public publishes that nonce to every site visitor. No account is required, and an attacker can submit question identifiers to retrieve correct answers for any configured quiz question.
