Improper Input Validation
A security issue was discovered in ingress-nginx prior to 1.2.0-beta.0 where a user that can create or update ingress objects can use the "spec.rules.http.paths.path" field of an Ingress object (in the networking.k8s.io or extensions API group) to obtain the credentials of the ingress-nginx controller. In the default configuration, that credential has access to all secrets in the cluster.
