Quiz Maker, CVE-2025-12426

CVE, Research URL: CVE-2025-12426
Home page URL: Security reports for Quiz Maker
Application: Quiz Maker
Published on: Nov 19, 2025
Research Description: The Quiz Maker plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 6.7.0.80. This is due to the plugin exposing quiz answers through the ays_quiz_check_answer AJAX action without proper authorization checks. The endpoint only validates a nonce, but that same nonce is publicly available to all site visitors via the quiz_maker_ajax_public localized script data. This makes it possible for unauthenticated attackers to extract sensitive data including quiz answers for any quiz question.
Affected versions: max 6.7.0.81.
Status: vulnerable
