SCA: security update for langflow (GHSA-cf6m-vc3m-7cgm)

critical Tenable Self-Hosted Container Security Plugin ID 473023

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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). (CVE-2026-8505)

Solution

Update the langflow library and its related packages to version 1.9.1 or later.
