CyberRota Analysis
AI-GeneratedRocket.Chat versions prior to 8.8.0 and several earlier releases are vulnerable due to insufficient schema validation in the Meteor DDP methods getThreadsList and getThreadMessages, allowing attackers to inject MongoDB operator objects. This flaw can lead to unauthorized disclosure of private thread information to low-privilege authenticated users, compromising sensitive data. Organizations using affected versions should prioritize patching to mitigate the risk of data exposure.

Original NVD Description
Rocket.Chat in versions before 8.8.0, 8.7.1, 8.6.2, 8.5.3, 8.4.6. 8.3.8, 8.2.8, 8.1.8, and 7.10.15, the Meteor DDP methods getThreadsList and getThreadMessages accept rid / tmid as raw, untyped parameters with no schema validation. A MongoDB operator object (e.g. {"$gt": "4"}) can be substituted for a string room-id or message-id. The authorization check resolves to a room the attacker already has access to, while the downstream data query fans out across all rooms - disclosing private thread parents and their full reply content to any low-privilege authenticated user. The REST route chat.getThreadsList was patched in v5.0 (HackerOne report #1446767) by adding rid: {type:'string'} AJV validation. The equivalent DDP method was never given the same fix and remains exploitable
