## Overview

OpenRemote core (openremote-manager) before 1.31.0 does not perform realm or gateway-descendant authorization on inbound edge gateway events and maps event asset IDs only through the reversible GatewayConnector.mapAssetId transform. An attacker controlling a registered gateway can craft pre-image IDs in AttributeEvent or DELETE AssetEvent messages to overwrite attributes on, or delete, assets in any realm, breaking tenant isolation.

## Affected

- `core < 1.31.0`
