What is CVE-2026-9202?

The IBM Langflow OSS software from version 1.0.0 to 1.10.0 contains a vulnerability that allows unauthenticated attackers to create an unlimited number of user accounts. If the deployment option NEW_USER_IS_ACTIVE is set to true, these accounts become immediately active, enabling attackers to authenticate and access remote code execution (RCE) endpoints without requiring automatic login. This vulnerability poses significant risks to users as it facilitates unauthorized access and potential exploitation.
