An authenticated user holding Synthetics privileges scoped to a single Kibana space could permanently delete Synthetics monitors that are shared into spaces they have no access to. Where a monitor is associated with a private location, the same operation also destroys the underlying Elastic Agent integration configuration without the authorization checks that Fleet would otherwise apply.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://discuss.elastic.co/t/kibana-8-19-22-9-4-7-9-5-3-security-update-esa-2026-139/390680","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
