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. A user with delegated GlobalRole create or update permission could point the annotation at any existing ClusterRole, such as `cluster-admin`, and revoke the permissions of every principal bound to it. The change persists after the malicious GlobalRole is deleted.\n\n\nThis issue affects Rancher: before 2.15.1.\n\n## Affected\n\n- `rancher < 2.15.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `rancher 2.15.1`","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":47.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
