  "title": "Code injection in Langflow code validation",
  "summary": "Langflow versions through 1.10.0 can execute attacker-supplied Python submitted to the code-validation endpoint. An attacker can run code with the privileges of the Langflow process; authentication is required in 1.7.2 through 1.10.0, except where automatic login permits access, while earlier versions exposed the endpoint without authentication.",
  "mitigation": "Upgrade Langflow to version 1.10.1 or later. Until upgraded, restrict access to the instance and disable automatic login to reduce exposure.",
