NVD description
Langflow Disk Cache Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Langflow. Authentication is required to exploit this vulnerability. The specific flaw exists within the disk cache service. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-27919.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Langflow off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
