Quick assessment

Affected
openremote core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 1.31.0 版本之前的 OpenRemote 核心组件（openremote-manager）中，对于传入的边缘网关事件未执行 realm（领域）或 gateway-descendant（网关后代）授权检查，且仅通过可逆的 转换函数映射事件中的资产 ID。若攻击者能够控制已注册的网关，即可在 或 消息中构造预映像 ID，从而覆盖任意 realm 中资产的属性，或删除这些资产，导致租户隔离机制被突破。

Vulnerability Title
OpenRemote before 1.31.0 Gateway Authorization Bypass via Reversible mapAssetId
Source: CVE Program / CVE List V5
Vulnerability Description
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.
