What is CVE-2026-67443?

FUXA, a web-based SCADA/HMI/Dashboard software, contains an authorization bypass vulnerability in versions 1.3.2 and earlier. The issue arises because the allowDashboard authorization check does not verify the decoded identity from the authJwt.verify call for the Node-RED integration. If certain configuration options are enabled, a remote attacker could exploit this weakness to gain access without proper authentication. This allows the attacker to potentially manipulate project data, configurations, scripts, and run operating-system commands by deploying malicious function nodes. The vulnerability has been patched in version 1.3.3.

Affected Version(s)

FUXA < 1.3.3
