Description
The eRoom plugin for WordPress is vulnerable to Privilege Escalation via the stm_zoom_meeting_sign AJAX action in all versions up to, and including, 1.7.1, due to the generate_signature() function taking the Zoom participant role from the request body without checking it. This makes it possible for unauthenticated attackers to obtain a Zoom Meeting SDK signature with the host role (role=1) for any published meeting or webinar, which, depending on the Zoom account's settings, can let them join that meeting with host privileges.
