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.","published":"2026-09-03T15:17:32.327","modified":"2026-09-03T15:17:32.327","cvss":{"score":8.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/rancher/rancher/pull/56593","label":"rancher/rancher#56593"},"references":[{"type":"WEB","url":"https://github.com/rancher/rancher/pull/56593"},{"type":"WEB","url":"https://github.com/rancher/rancher/pull/56642"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-03T15:17:32.327"}}
