Unauthenticated data disclosure via Socket.IO SSRF
Published Aug 18, 2026 · Updated Aug 18, 2026
Server-side request forgery in Frangoteam FUXA before 1.3.2 allows remote attackers to read internal or cloud-hosted data via Socket.IO events. The DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY handlers in server/runtime/index.js skip isSocketWriteAuthorized, pass attacker-controlled URLs or endpoint data into axios, OPC UA, or ODBC requests, and return the results on the corresponding Socket.IO event. No authentication or operator interaction is required, and secureEnabled=true does not block access, so any service reachable from the FUXA host can become a read-only SSRF target.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
