What an attacker can do

Unauthenticated attackers can create unlimited user accounts on any Langflow instance; when NEW_USER_IS_ACTIVE=true (documented deployment option), newly created accounts are immediately active and can authenticate to reach RCE endpoints, bypassing the need for AUTO_LOGIN. Vendor/CNA’s CVSS 3.1 assessment (base score 9.8/10) rates confidentiality, integrity and availability impact as high.
