SCA: security update for langflow (GHSA-v8hw-mh8c-jxfc)

critical Tenable Self-Hosted Container Security Plugin ID 439338

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. Prior to version 1.9.0, the
Agentic Assistant feature in Langflow executes LLM-generated Python code during its validation phase.
Although this phase appears intended to validate generated component code, the implementation reaches
dynamic execution sinks and instantiates the generated class server-side. In deployments where an attacker
can access the Agentic Assistant feature and influence the model output, this can result in arbitrary
server-side Python execution. Version 1.9.0 fixes the issue. (CVE-2026-33873)

Solution

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