CVE-2026-116186: OpenRemote core authorization bypass via reversible asset ID mapping

CVE-2026-116186 · Severity: info · Published 2026-10-25

OpenRemote is an open-source IoT platform that manages connected devices and assets across multiple tenant organizations. A flaw in how edge gateways are authorized allows an attacker who controls a registered gateway to craft malicious events that bypass security checks, enabling them to modify or delete assets belonging to any tenant in the system. This breaks the isolation between organizations and could allow an attacker to manipulate critical IoT systems or destroy infrastructure data across the entire deployment.

Technologies: OpenRemote Core. Vendors: OpenRemote.

How to fix

  • Fixed in: 1.31.0

Technical details

The GatewayConnector.mapAssetId transform is mathematically reversible—an attacker who owns a gateway can invert it to craft asset IDs that map to any asset in any realm. Inbound gateway events skip realm and descendant authorization checks; onAttributeEvent and onAssetEvent (DELETE) process events based solely on the mapped asset ID without validating authorization scope. An authenticated gateway user can thus overwrite arbitrary attributes or delete assets across all tenants.

Affected products
