Description Kurt Seifried 2015-08-19 17:02:17 UTC 
Cesar Wong of Red Hat reports:

Exec operations should be forbidden to privileged pods such as builder pods 
because they have privileged access to nodes. Currently, you can exec into any 
builder pod, getting privileged root access to the node it's running on.
