CVE-2026-33892Network attack vector

Unauthenticated device tunneling via authentication bypass

Published Apr 14, 2026 · Updated Apr 14, 2026

Authentication bypass in Siemens Industrial Edge Management allows remote attackers to tunnel to connected Industrial Edge Devices. The remote-connection path fails to enforce management-user authentication; Siemens discloses only that the expected header and service port must be identified. Exploitation also requires the device's remote-connection feature to be enabled; authentication inside the connected device remains enforced.
