Advisory
Source description from Wordfence Intelligence, credited to Jonas Benjamin Friedli.
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.
