The Quiz Master Next plugin for WordPress is vulnerable to SQL Injection via stored quiz page data in versions up to, and including, 11.2.0. This is due to insufficient escaping on the user-supplied 'pages' parameter persisted by the qsm_ajax_save_pages() AJAX handler (sanitize_text_field only) and lack of sufficient preparation on the existing SQL query built in qsm_options_questions_tab_content() at line 143, where the stored page IDs are interpolated into an IN() clause via implode() with no $wpdb->prepare() and no integer casting. This makes it possible for authenticated attackers, with Author-level access and above (who can own a quiz they are entitled to edit), to plant a SQL payload that is executed second-order whenever any user (including an administrator) views the quiz's Questions tab, allowing them to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
