Description
The One to one user Chat by WPGuppy plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the /wp-json/guppylite/v2/channel-authorize rest endpoint in all versions up to, and including, 1.1.4. This makes it possible for unauthenticated attackers to intercept and view private chat messages between users.
