Advisory

Source description from Wordfence Intelligence, credited to abrahack.

The Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency). 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. NOTE: The three variations of this software (Business, Developer, and Agency) share the same plugin slug, so you may get an alert even if you are running the latest version of any of the pieces of software. In these cases it is safe to dismiss the notice once you've confirmed your site is on a patched version of the applicable software.
