Technical details

An improper access control vulnerability (CWE-284) exists in the Rocket.Chat DDP method 'autoTranslate.translateMessage'. The method accepts a client-supplied 'IMessage' object and passes it to the translation logic without verifying the 'Meteor.userId()' or checking if the requesting user has membership in the room associated with the message. An authenticated attacker can exploit this by calling the method with a specific message ID to retrieve the content of any message, bypassing restrictions for private channels, direct messages (DMs), and end-to-end encrypted (E2EE) rooms. The issue is resolved in versions 8.5.0, 8.4.2, 8.3.4, 8.2.4, 8.1.5, 8.0.5, 7.13.8, and 7.10.12.
