CVE-2026-13767Network attack vector

Authenticated database disclosure via stored SQL injection

Published Jul 16, 2026 · Updated Jul 16, 2026

SQL injection in Quiz and Survey Master 11.2.0 and earlier allows remote authenticated users to read database data via stored quiz page IDs. The qsm_ajax_save_pages() AJAX handler stores the pages parameter after only sanitize_text_field(), and qsm_options_questions_tab_content() later joins those values into an IN() clause without integer casting or $wpdb->prepare(). Author-level access plus ownership and edit rights for a quiz are required; the payload executes when its Questions tab is viewed.
