CVE-2026-116184 · Severity: info · Published 2026-10-25

OpenRemote is a management platform for IoT gateways and connected devices. A cross-realm authorization flaw allows an administrator in one tenant realm to impersonate gateways in other realms, potentially overwriting device configurations and opening unauthorized network access tunnels. An attacker would need legitimate admin rights in their own realm and knowledge of a target gateway's ID to exploit this.

## How to fix

- Fixed in 1.31.0

## Technical details

GatewayService validates incoming websocket messages by gateway ID alone without checking the realm of the authenticated service user, allowing attackers with WRITE:ADMIN privileges in one realm to create a service account matching a gateway ID from another realm and connect to that realm's GatewayConnector. Via this impersonation, an attacker can perform CRUD operations on descendant assets, create SSH tunnels, and modify gateway configurations in the target realm. The vulnerability requires network access, high privileges in a source realm, knowledge of the target gateway ID, and manual attack complexity; a fix is available in version 1.31.0.
