Description
The Quiz and Survey Master (QSM) plugin for WordPress up to version 11.2.7 contains a code injection vulnerability that allows unauthenticated attackers to execute arbitrary shortcodes. This occurs because the plugin improperly validates input before calling do_shortcode, and the nonce used for submission is accessible without authentication, providing no effective protection against exploitation.
