critical Tenable Self-Hosted Container Security Plugin ID 443285

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 1.9.2, the
"Shareable Playground" (or "Public Flows" in code) contains a critical RCE vulnerability. Shareable
Playground feature works by enabling the execution of workflows by unauthenticated users, by accessing a
link. Specifically, it enables the route /api/v1/build_public_tmp to execute any public flow, given a
public flow ID. When the route executes the flow, it allows for providing arbitrary custom Python code as
the nodes code, inside the JSON payload. The vulnerable field is
data.nodes[X].data.node.template.code.value. This vulnerability is fixed in 1.9.2. (CVE-2026-48519)

Solution

Update the langflow library and its related packages to version 1.9.2 or later.
