SCA: security update for langflow (GHSA-g2j9-7rj2-gm6c)

critical Tenable Self-Hosted Container Security Plugin ID 439247

Description

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

 - Langflow is a tool for building and deploying AI-powered agents and workflows. Versions 1.2.0 through
 1.8.1 have a bypass of the patch for CVE-2025-68478 (External Control of File Name), leading to the root
 architectural issue within `LocalStorageService` remaining unresolved. Because the underlying storage
 layer lacks boundary containment checks, the system relies entirely on the HTTP-layer `ValidatedFileName`
 dependency. This defense-in-depth failure leaves the `POST /api/v2/files/` endpoint vulnerable to
 Arbitrary File Write. The multipart upload filename bypasses the path-parameter guard, allowing
 authenticated attackers to write files anywhere on the host system, leading to Remote Code Execution
 (RCE). Version 1.9.0 contains an updated fix. (CVE-2026-33309)

Solution

Update the langflow library and its related packages to version 1.9.0 or later.
