Summary

Duplicate Advisory: Unauthenticated Flow Execution via Webhook Authentication Bypass

Details

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This advisory has been withdrawn because it is a duplicate of GHSA-cf6m-vc3m-7cgm.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 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).
