CyberRota Analysis

AI-Generated

IBM Langflow OSS versions 1.0.0 to 1.10.0 are vulnerable due to a flaw in the webhook authentication logic that allows unauthenticated users to execute any flow by bypassing API key validation when the WEBHOOK_AUTH_ENABLE setting is disabled (default). This critical vulnerability could lead to Remote Code Execution (RCE) if an attacker knows the UUID of a flow. Organizations using affected versions should prioritize immediate remediation to mitigate the risk of unauthorized access and potential exploitation.

Original NVD 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).
