Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in Rancher 2 through 2.1.5. Any project member with access to the default
 namespace can mount the netes-default service account in a pod, and then use that pod to execute
 administrative privileged commands against the k8s cluster. This could be mitigated by isolating the
 default namespace in a separate project, where only cluster admins can be given permissions to access. As
