## Overview

OpenRemote notification deletion endpoints fail to enforce realm boundaries, allowing any realm administrator to delete notifications belonging to other realms. Attackers with write:admin role in one realm can send DELETE requests to remove notifications from the master realm or other tenants without authorization checks.
