The hook
FUXA is used to build SCADA and HMI dashboards, so authentication is part of the safety boundary, not just a convenience feature. CVE-2025-69971 affects deployments that rely on a known fallback JWT signing configuration instead of a unique deployment secret.
Hoe dit werk
FUXA deployments affected by CVE-2025-69971 can trust tokens signed through an insecure fallback configuration. The risk is authentication bypass into administrative SCADA/HMI functionality.
The blast radius
A confirmed exposure can allow administrative access to the FUXA instance. In an industrial dashboard context, that can expose project configuration, users, devices, plugins, and operational views, and may become a path to broader control-plane compromise.

What FixVibe checks
FixVibe checks this class with verified-domain active testing that is bounded, non-destructive, and evidence-driven. Public reports describe the affected surface and remediation.

Ironclad defenses
Upgrade FUXA to 1.3.0 or newer, configure a unique high-entropy JWT secret for the deployment, restart the service, and invalidate existing sessions. Keep FUXA management interfaces behind VPN, SSO, or trusted-network restrictions where practical.
