CVE-2026-42922 · Severity: critical · CVSS 9.8 · Published 2026-10-29

FUXA is an open-source HMI (human-machine interface) software that allows users to build dashboards for monitoring and controlling industrial processes. The software optionally integrates Node-RED, a visual programming tool for automation. An unauthenticated attacker can bypass authorization checks and gain access to Node-RED, allowing them to deploy malicious flows that execute arbitrary code on the server running FUXA.

## Technical details

The /nodered authorization callback fails to properly restrict access based on identity, accepting any valid JWT token regardless of permission level. An unauthenticated user can obtain a guest JWT from the /api/heartbeat endpoint, which the authorization callback accepts as valid, allowing unauthorized access to Node-RED functionality and subsequent arbitrary code execution through malicious flow deployment.
