CVSS 9.8 · Critical EPSS 0,72%

Kerentanan Missing Authentication for Critical Function pada langflow. Skor CVSS 3.1 9.8 (Critical) menurut us.ibm.com.

Deskripsi (NVD)

IBM Langflow OSS 1.0.0 through 1.10.0 has a vulnerability in Langflow's webhook authentication logic allows unauthenticated users to trigger the execution of any flow. The system incorrectly bypasses API key validation when the WEBHOOK_AUTH_ENABLE configuration is set to False (which is the default setting). This allows a remote attacker who knows a flow's UUID to execute it as if they were the owner, potentially leading to Remote Code Execution (RCE).
