SCA: security update for flowise (GHSA-9rvc-vf7m-pgm2)

critical Tenable Cloud Security Plugin ID 441880

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 version
3.1.2, POST /api/v1/node-custom-function lacks route-level authorization, allowing any authenticated user
or API key to submit arbitrary JavaScript to the Custom JS Function node. When E2B_APIKEY is not
configured — the common deployment case — Flowise executes this code inside a NodeVM sandbox. This sandbox
can be escaped, allowing an attacker to reach the host process object and execute system commands via
child_process. The result is authenticated remote code execution on the Flowise server host. This issue
has been patched in version 3.1.2. (CVE-2026-46442)

Solution

Update the flowise library and its related packages to version 3.1.2 or later.
