RumbleTalk Live Group Chat < 6.2.0 - Missing Authorization via handleRequest

Description

The RumbleTalk Live Group Chat plugin for WordPress is vulnerable to unauthorized access of data, modification of data, and loss of data due to a missing capability check on the handleRequest AJAX function in versions up to, and including, 6.1.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve or update tokens, create, update, refresh, and delete chats, and create accounts.
