Rancher: Ownership-less ClusterRole overwrite via attacker-controlled cr-name annotation on GlobalRole
Vulnerability Description
A flaw was found in Rancher Manager. The GlobalRole controller derived the target ClusterRole name from the user-settable `authz.management.cattle.io/cr-name` annotation and overwrote that object's rules without verifying ownership.

The change persists after the malicious GlobalRole is deleted.
This issue affects Rancher: before 2.15.1.
