The The Quiz and Survey Master (QSM) – Quiz Maker & Survey Maker plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 11.2.7. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. The submission nonce is dispensed to any unauthenticated caller by the public wp_ajax_nopriv_qsm_create_quiz_nonce endpoint, meaning it functions as a CSRF token rather than an authorization barrier and imposes no meaningful obstacle to exploitation.
