Duplicate Advisory: Unauthenticated Flow Execution via Webhook Authentication Bypass

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-cf6m-vc3m-7cgm. This link is maintained to preserve external references.

Original Description

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 WEBHOOKAUTHENABLE 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).
