Description

A security issue was discovered in ingress-nginx https://github.com/kubernetes/ingress-nginx where the mirror-target and mirror-host Ingress annotations can be used to inject arbitrary configuration into nginx.

(Note that in the default installation the controller can access all Secrets cluster-wide.)
