This makes it possible for authenticated attackers, with custom-level access and above, to access the full message transcript, thread metadata, and user data of any chat-room thread without authentication. This is only exploitable when the chat room's only_joined_can_read setting retains its default value of '0'."}], "lastModified": "2026-09-21T13:33:33.387", "sourceIdentifier": "security@wordfence.com"}
