SCA: security update for flowise, flowise-components (GHSA-4j8x-x6v7-w9rq)

critical Tenable Cloud Security Plugin ID 445636

Description

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

 - Prior to 3.1.3, Flowise CSVAgent interpolates an attacker-controlled segment of the csvFile data URI
 directly into a Python source-code template that is then executed by Pyodide. Because Pyodide is loaded
 with the default js bridge to globalThis, which on Node.js exposes eval and dynamic import, the attacker
 can break out of the Python string literal, hand a JavaScript string to js.eval, dynamically import Node
 built-in modules such as fs and child_process, and execute arbitrary file I/O or OS commands as the
 Flowise process. The two validator paths around this code, validatePythonCodeForDataFrame and
 validateCustomReadCSVFunction, are never applied to the bootstrap template. A workspace user with
 chatflows:create or agentflows/chatflows update permission can plant a CSV Agent node with a crafted
 csvFile; once the chatflow is exposed via POST /api/v1/prediction/:id, any unauthenticated request
 triggers host remote code execution. This issue is fixed in version 3.1.3. (CVE-2026-69264)

Solution

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