Technical details
The plugin lacks proper authorization checks before granting access to chat room data, allowing authenticated users with custom-level access and above to read message transcripts and metadata regardless of the chat room's join status. The vulnerability requires the chat room's only_joined_can_read setting to remain at its default value of 0. An attacker with authenticated access can enumerate and retrieve sensitive chat data through direct API or function calls.
