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."}],"affected":[{"source":"meissner@suse.de","affectedData":[{"vendor":"SUSE","product":"Rancher","defaultStatus":"unaffected","repo":"https://github.com/rancher/rancher","versions":[{"version":"0","lessThan":"2.15.1","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"meissner@suse.de","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H","baseScore":8.7,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.3,"impactScore":5.8}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-03T15:06:03.098792Z","id":"CVE-2026-71404","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"meissner@suse.de","type":"Secondary","description":[{"lang":"en","value":"CWE-639"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:suse:rancher:*:*:*:*:*:*:*:*","versionEndExcluding":"2.15.1","matchCriteriaId":"C911F079-FC7A-48EB-9A06-C86AFC6FC1AD"}]}]}],"references":[{"url":"https://github.com/rancher/rancher/pull/56593","source":"meissner@suse.de","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/rancher/rancher/pull/56642","source":"meissner@suse.de","tags":["Issue Tracking","Patch"]}]}}
