{"id":"BIT-elk-2026-72664","summary":"Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions","details":"Missing Authorization (CWE-862) in Kibana can lead to unauthorized execution of Elastic Defend response actions on managed hosts via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). A Kibana user who holds only detection rule authoring privileges for the Elastic Security solution can associate automated endpoint response actions with a detection rule, even though the dedicated Endpoint response action privileges that govern those capabilities (host isolation, process operations, and execute operations) have not been granted to that user. When such a rule generates alerts, the associated response actions are carried out against the matching hosts.","aliases":["BIT-kibana-2026-72664","CVE-2026-72664"],"modified":"2026-09-08T08:47:07.468643797Z","published":"2026-08-19T08:40:34.561Z","database_specific":{"cpes":["cpe:2.3:a:elasticsearch:kibana:*:*:*:*:*:node.js:*:*"],"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://discuss.elastic.co/t/kibana-8-19-20-and-9-4-5-security-update-esa-2026-95/389527"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72664"}],"affected":[{"package":{"name":"elk","ecosystem":"Bitnami","purl":"pkg:bitnami/elk"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.9.0"},{"fixed":"8.19.20"},{"introduced":"9.0.0"},{"fixed":"9.4.5"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/elk/BIT-elk-2026-72664.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.9.0"}
