CVE-2026-6448Network attack vector

Authenticated database disclosure via unprepared order parameter

Published Jun 5, 2026 · Updated Jun 5, 2026

SQL injection in Quiz and Survey Master 11.1.2 and earlier allows remote authenticated users to extract database data via the order parameter. The class-qsm-quiz-api.php query-building path places the user-supplied order value into an existing SQL query without sufficient escaping or prepared-query handling. Administrator access is normally required; exposure of the plugin secret key lowers the privilege gate, and successful exploitation discloses sensitive database information.
