Overview
k8s.io/kubernetes/plugin/pkg/auth/authorizer/rbac/bootstrappolicy is a package rbac that implements the authorizer.Authorizer interface using roles base access control.
Affected versions of this package are vulnerable to Access Restriction Bypass. Endpoint & EndpointSlice permissions allow cross-Namespace forwarding. If a potential attacker can create or edit Endpoints or EndpointSlices in the Kubernetes API, they can potentially direct a LoadBalancer or Ingress implementation to expose backend IPs the attacker should not have access to.
