critical Tenable Self-Hosted Container Security Plugin ID 443350

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 1.9.1,
 unauthenticated users can upload any amount of data to the server without any limitations. No need for any
 prior knowledge, only network access to Langflow. This can lead to space exhaustion on the server. In
 addition, in the response, the absolute path of the uploaded file is reported to the attacker, which is an
 information leak that can assist in chaining other primitives. This vulnerability is fixed in 1.9.1.

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