A flaw was found in ovn-kubernetes.

Description Sam Fowler 2022-02-11 00:52:07 UTC 
When using ovn-kubernetes on a Kubernetes or OpenShift cluster, it is possible to create an egress network policy that bypasses existing an ingress policy, allowing netwrok traffic to access pods that should not be reachable. This attack is limited to pods on the same node.
