CVE-2026-41166
Description
OpenRemote is an open-source internet-of-things platform. Prior to version 1.22.1, a user who has write:admin in one Keycloak realm can call the Manager API to update Keycloak realm roles for users in another realm, including master. The handler uses the {realm} path segment when talking to the identity provider but does not check that the caller may administer that realm. This could result in a privilege escalation to master realm administrator if the attacker controls any user in master realm. Version 1.22.1 fixes the issue.
