## Description

The eRoom plugin for WordPress is vulnerable to unauthorized modification and loss of data via the stm_zoom_delete_from_api AJAX action in all versions up to, and including, 1.7.1, due to a missing capability check. The handler checks only a nonce, and that nonce is printed on every admin page to any logged-in user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary meetings or webinars from the connected Zoom account and remove the Zoom meeting data stored on any post.
