CVE-2026-47719 · Severity: high · CVSS 8.2 · Published 2026-08-18

FUXA is an open-source web-based SCADA/HMI system used to monitor and control industrial processes. A security flaw allows unauthenticated attackers to use the FUXA server as a proxy to access internal network services, cloud metadata, or private databases. This could lead to the theft of sensitive credentials, exposure of internal industrial equipment, or unauthorized access to corporate data.

Technologies: [Frangoteam FUXA](https://junglewise.ai/threats/technologies/fuxa), [fuxa-server (npm)](https://junglewise.ai/threats/technologies/fuxa-server). Vendors: [Frangoteam](https://junglewise.ai/threats/vendors/frangoteam), [npm](https://junglewise.ai/threats/vendors/npm).

## Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in FUXA's Socket.IO implementation due to missing authorization checks in the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY event handlers. An unauthenticated attacker can emit these events with arbitrary URLs or connection strings, which the server then processes using axios or database drivers. Because the server broadcasts the response body back to the client via io.emit, the attacker can read the results of these requests. This allows for scanning internal networks, exfiltrating cloud instance metadata (IAM credentials), and interacting with internal OPC UA or ODBC services. The vulnerability is present even when authentication is enabled because the system auto-issues guest tokens to new connections. A fix is available in version 1.3.2.
