SCA: security update for flowise, flowise-components (GHSA-5xvg-pmgg-3mxr)

critical Tenable Cloud Security Plugin ID 445654

Description

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

- Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, a
prompt injection sent to a chatflow using a CSV Agent node can cause the LLM to respond with a malicious
Python script that bypasses the blocklist validator and executes in an unsandboxed Pyodide environment.
The specific flaw exists within the run method of the CSV_Agents class, where untrusted data is used to
construct an LLM prompt and the resulting pythonCode is validated by validatePythonCodeForDataFrame before
execution. An attacker can leverage this to execute arbitrary code in the context of the service account.
This issue is fixed in 3.1.3. (CVE-2026-70477)

Solution

Update the flowise library and its related packages to version 3.1.3 or later.
