CVE-2026-73843: OpenChoreo: Unauthenticated access to data-plane operations via OpenChoreo cluster-gateway management APIs

The OpenChoreo control-plane cluster-gateway served its caller-facing management APIs on the same network listener that accepts data-plane agent connections. In the multi-cluster topology that listener is published outside the cluster, and the management APIs did not authenticate the calling client. A party able to reach the listener could therefore invoke privileged data-plane operations without authenticating and without passing through the OpenChoreo API server’s authorization.
