Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to 8.5.0, 8.4.1, 8.3.3, 8.2.3, 8.1.4, 8.0.5, 7.13.7, and 7.10.11, Rocket.Chat's sendFileMessage DDP method passes the entire attacker-supplied file object into Uploads.updateFileComplete, which merges it directly into a MongoDB $set update via Object.assign. There is no allow-list of writable fields. An attacker can therefore rewrite any column on their own upload record, notably store and the store-specific path fields. This vulnerability is fixed in 8.5.0, 8.4.1, 8.3.3, 8.2.3, 8.1.4, 8.0.5, 7.13.7, and 7.10.11.
