Descriptions

The Quiz And Survey Master for WordPress is vulnerable to authorization bypass due to a missing capability check on the function associated with the qsm_remove_file_fd_question AJAX action in versions up to, and including, 8.0.8. This makes it possible for unauthenticated attackers to delete arbitrary media files.

WordPress Quiz and Survey Master plugin versions 8.0.8 and below suffer from a missing authentication vulnerability that allows an attacker to delete media from the WordPress instance.
