CVE-2026-25752Network attack vector

Unauthenticated device manipulation via Socket.IO authorization gap

Published Feb 6, 2026 · Updated Feb 6, 2026

Missing authorization in FUXA before 1.2.10 allows remote attackers to write device tags or disable drivers through Socket.IO. The runtime Socket.IO layer accepts guest device-values requests with cmd set and device-enable actions without enforcing authorization for write and device-management operations. No authentication or user interaction is required, and even secure-enabled deployments expose connected control processes to unauthorized value changes or communication loss.
