Vendor: Kubernetes Product: ingress-nginx Package: ingress-nginx-controller-1.12 Package: k8s.io/ingress-nginx Ecosystem: Go Ecosystem: Wolfi

Description

A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
