DescriptionCVE.org

The Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to generic SQL Injection via the 'qpages' parameter in all versions up to, and including, 11.2.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The injected payload survives storage and a published-status check in display_shortcode() because a non-numeric ID causes the isPublished lookup to return an empty string, after which the payload is imploded directly into a WHERE question_id IN() clause via plain string interpolation with no wpdb->prepare() or esc_sql() call.
