## Technical details

The vulnerability exists in the `/api/v1/autotranslate.translateMessage` endpoint due to a lack of authorization checks. The endpoint uses `Messages.findOneById(messageId)` to fetch message data but fails to invoke `canAccessRoomIdAsync` or any equivalent room access validation. An authenticated attacker can exploit this by supplying a target `messageId` to the endpoint, which returns the complete `IMessage` object. This object includes sensitive fields such as the message text, sender information, room ID, timestamps, and markdown content, regardless of whether the user is a member of the room where the message originated.
