Video Conferencing with Zoom <= 4.4.5 - Sensitive Information Exposure

The Video Conferencing with Zoom plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.5 via the get_assign_host_id AJAX action. This makes it possible for authenticated attackers, with subscriber access or higher, to enumerate usernames, emails and IDs of all users on a site.
