Openremote

An incomplete fix for CVE-2026-40882 in OpenRemote's KNXProtocol module (specifically in versions <= 1.24.1 of the agent module) allows authenticated users to perform an XML External Entity (XXE) injection, enabling arbitrary file read from the server's filesystem, including sensitive configuration files and potentially leading to server-side request forgery (SSRF) against cloud metadata endpoints or internal services, without requiring administrator access.

A high-severity vulnerability (CVE-2026-54641) in OpenRemote's `UserResourceImpl.java` allows a realm administrator in a multi-tenant deployment to perform cross-realm user enumeration and privilege-level reconnaissance by reading sensitive user information (profile, client roles, and realm roles) from any other realm, including the master realm, due to missing authorization checks in specific REST API endpoints.

The OpenRemote IoT platform is vulnerable to expression injection, allowing remote code execution due to an unsandboxed Nashorn JavaScript engine and an inactive Groovy sandbox, leading to full server compromise.

OpenRemote is vulnerable to privilege escalation, allowing an attacker with write:admin privileges in one Keycloak realm to gain administrator access to the master realm by manipulating Keycloak realm roles due to missing authorization checks in the updateUserRealmRoles function.
