Description Mark Cooper 2020-06-24 07:49:25 UTC 
In all versions of servicemesh-operator through 1.1.3, when deploying the Service Mesh control plane the operator will deploy the ingress gateway to any namespace regardless of the current user's permissions. Additionally the image deployed as the gateway can also be specified by a user. An attacker with basic cluster permissions can exploit this to deploy their own pod into a namespace owned by kube-admin, possibly gaining access to privileged service account tokens.
