Description
The Better Messages plugin for WordPress has an authorization bypass vulnerability in all versions up to and including 2.15.33. This flaw allows authenticated users with custom-level access or higher to access message transcripts, thread metadata, and user data of any chat-room thread without proper authorization. Exploitation requires the chat room setting 'only_joined_can_read' to be set to its default value of '0'.
