Explaining security vulnerabilities addressed in Rancher v2.1.6 and v2.0.11

Today we announced releases v2.1.6 and v2.0.11 to address two security vulnerabilities recently discovered in Rancher. The first vulnerability allows users in the Default project of a cluster to escalate privileges to that of a cluster admin through a service account. The second vulnerability allows members to have continued access to create, update, read, and delete namespaces in a project after they have been removed from it. You can view the official CVEs here CVE-2018-20321 and here CVE-2019-6287.
