A malicious UI extension could abuse that to:  *  Overwrite Rancher binaries or configuration to inject code.\n\n  *  Write to /var/lib/rancher/ to tamper with cluster state.\n\n  *  If hostPath volumes are mounted, write to the host node filesystem.\n\n  *  Use this issue to chain with other attack vectors.","published":"2026-05-13T08:16:16.000Z","lastModified":"2026-10-26T14:10:00.000Z","status":"Awaiting Analysis","sourceIdentifier":"meissner@suse.de","cvss":{"version":"3.1","score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H"},"cwe":["CWE-35"],"affected":[],"epss":{"score":0.00369,"percentile":0.30492,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%).
