Description
Tamery (formerly Conar) 0.26.1 before 0.99.0 contains an authorization bypass vulnerability in the cloud sync API chatsMessages.update handler, which leaves the client-supplied chatId writable. Authenticated Pro subscribers who know another user's chat ID can move messages with arbitrary parts and metadata into the victim's AI chat history.
