CVE-2026-71404
8.7
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H
Summary
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. 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.
This issue affects Rancher: before 2.15.1.
