Auth bypass in Openremote Core

CVE-2026-116184

OpenRemote before 1.31.0 contains an authorization bypass vulnerability that allows realm admins to impersonate gateways in other realms because GatewayService only checks the gateway ID, not the realm. Attackers with WRITE:ADMIN in one realm can create a service user named after another realm's gateway ID to overwrite its descendant assets and open SSH tunnels into its local network.
