Openshift-dedicated: must-gather-operator: yaml template injection leads to privilege escalation

A flaw was found in the MustGather.managed.openshift.io Custom Defined Resource (CRD) of OpenShift Dedicated. A non-privileged user on the cluster can create a MustGather object with a specially crafted file and set the most privileged service account to run the job. This can allow a standard developer user to escalate their privileges to a cluster administrator and pivot to the AWS environment.
