CVE-2026-47719
Prior to 1.3.2, the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY Socket.IO handlers in server/runtime/index.js omit isSocketWriteAuthorized and accept attacker-controlled property.address or endpoint connection data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY Socket.IO handlers in server/runtime/index.js omit isSocketWriteAuthorized and accept attacker-controlled property.address or endpoint connection data. A remote unauthenticated attacker can make server/runtime/devices/httprequest/index.js call axios.get against arbitrary HTTP or HTTPS destinations, connect to reachable OPC UA or ODBC services, and receive results through the corresponding Socket.IO event. This read SSRF oracle can expose cloud instance metadata, internal administrative services, industrial endpoints, and ODBC data reachable from the FUXA host, including when secureEnabled is true. This issue is fixed in version 1.3.2.
