## Description

The eRoom plugin for WordPress is vulnerable to unauthorized modification of data via the stm_zoom_sync_meetings_webinars AJAX action in versions 1.3.8 up to, and including, 1.7.1, due to a missing capability check. The 1.3.8 fix for the earlier unauthorized setting update in this handler added only a nonce 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 trigger a synchronization that creates or updates meetings in the connected Zoom account and creates or updates meeting posts on the site.
