CVE-2026-40063 · Severity: medium · CVSS 5.3 · Published 2026-10-29

FUXA is an open-source web-based HMI software that allows operators to build dashboards and remotely interact with industrial processes. When Node-RED integration is enabled, an unauthenticated attacker can retrieve the names and identifiers of all configured scripts on the system through the /nodered/fuxa/scripts endpoint, bypassing normal authorization controls. This information disclosure can enable subsequent attacks on privileged scripts, potentially leading to unauthorized control of industrial systems.

Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-40063 attacked?** It is attacked over the network, in a web application.

**Am I affected by CVE-2026-40063?** Check whether you run Frangoteam FUXA at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in 1.3.3

Disable Node-RED integration unless required for internal/trusted environments only, and ensure appropriate network-level access controls are in place to restrict access to the /nodered routes.

## Technical details

The /nodered/fuxa/scripts GET endpoint in server/integrations/node-red/index.js fetches all project scripts and returns their identifiers and names without authorization filtering, despite similar endpoints in the main /api/ routes applying permission-based content filtering. An unauthenticated attacker can make an HTTP request to retrieve this information, which is particularly dangerous when combined with authorization bypass vulnerabilities (TALOS-2026-2417, TALOS-2026-2419) that allow script execution abuse. The vulnerability requires Node-RED to be enabled, which is disabled by default.
