kubernetes ingress-nginx Published: (1 year ago)

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.)
