CVE-2026-30831 describes authentication vulnerabilities in Rocket.Chat's enterprise DDP Streamer service, affecting versions prior to 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0. The Account.login method in the DDP Streamer fails to enforce Two-Factor Authentication (2FA) and allows deactivated users to log in, bypassing standard security checks. This vulnerability is rated High severity (CVSS 8.0) due to its network-based attack vector and low attack complexity, potentially leading to unauthorized access and compromise of user accounts. There is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog, though it has received minimal community discussion.
