CVE-2026-47717 · Severity: high · CVSS 7.5 · Published 2026-08-12

FUXA, an open-source industrial monitoring and control (HMI/SCADA) platform, contains a security flaw that allows unauthorized users to download entire project configurations. This includes sensitive information such as server-side automation scripts, device connection details, and alarm settings. An attacker could use this data to understand internal operations or plan more disruptive attacks against industrial infrastructure.

## Technical details

The `/api/project` endpoint in FUXA v1.3.0 fails to enforce proper authentication due to a flaw in the `verifyToken` middleware. When no authentication token is provided, the system automatically generates and signs a valid 'guest' JWT, which passes the security check. While some UI elements are filtered, the backend response still includes sensitive metadata such as full server-side script source code, device communication endpoints, HMI SVG layouts, and alarm thresholds. This is classified as an insertion of sensitive information into sent data (CWE-201). The vulnerability is addressed in version 1.3.1.
