SCA: security update for flowise, flowise-components (GHSA-52fh-8v99-63c2)

critical Tenable Self-Hosted Container Security Plugin ID 445621

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,
 Flowise validatePythonCodeForDataFrame in packages/components/src/pythonCodeValidator.ts can be bypassed
 with Unicode homoglyph identifiers, allowing arbitrary Python execution inside Pyodide and full OS command
 execution on the Flowise host via Pyodide js module interop. The validator gates pyodide.runPythonAsync in
 packages/components/nodes/agents/CSVAgent/CSVAgent.ts and
 packages/components/nodes/agents/AirtableAgent/AirtableAgent.ts with an ASCII word-boundary blacklist.
 JavaScript regex word boundaries are ASCII-only, while Python 3 NFKC-normalizes identifiers at parse time,
 so homoglyph forms such as __cl𝐚ss__, __subcl𝐚sses__, __b𝐚se__, and __b𝐮iltins__ bypass the blacklist and
 are parsed as their ASCII equivalents. This issue is fixed in version 3.1.3. (CVE-2026-70470)

Solution

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