Summary
Rancher does not properly specify ApiGroup when creating Kubernetes RBAC resources
Details

A vulnerability was discovered in Rancher versions 2.0 through the aforementioned fixed versions, where users were granted access to resources regardless of the resource's API group. For example Rancher should have allowed users access to apps.catalog.cattle.io, but instead incorrectly gave access to apps.*. Resource affected include:
