Description
The Video Conferencing with Zoom plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.6.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to obtain the site's Zoom SDK API key and a freshly-signed JWT that can be used with the Zoom Web SDK to join any Zoom meeting associated with those credentials without a legitimate invitation.
