A non-administrative user able to edit a shared agent could cause privileged operations to be carried out under the identity of a higher-privileged user who subsequently interacts with that agent. Where the same user can also author workflows, this can extend to full administrative control of Kibana and of the Elasticsearch cluster.","published":"2026-09-26T21:16:56.000Z","lastModified":"2026-09-29T04:17:57.000Z","status":"Awaiting Analysis","sourceIdentifier":"security@elastic.co","cvss":{"version":"3.1","score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N"},"cwe":["CWE-441"],"affected":[],"epss":{"score":0.00185,"percentile":0.07972,"date":"2026-10-27","history":[{"date":"2026-09-27","score":0.00178,"percentile":0.06562}]},"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 (0.18%).
