{"id":"CVE-2026-72664","state":"PUBLISHED","title":"Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions","description":"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.","publishedAt":"2026-08-13T19:11:30.066Z","updatedAt":"2026-08-14T16:38:42.016Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","source":"elastic"},"assigner":"elastic","products":["Elastic Kibana"],"affected":[{"vendor":"Elastic","product":"Kibana","defaultStatus":"unaffected","versions":[{"version":"8.9.0","status":"affected","lessThanOrEqual":"8.19.19","versionType":"semver"},{"version":"9.0.0","status":"affected","lessThanOrEqual":"9.4.4","versionType":"semver"}]}],"references":["https://discuss.elastic.co/t/kibana-8-19-20-and-9-4-5-security-update-esa-2026-95/389527"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72664.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72664","state":"PUBLISHED","datePublished":"2026-08-13T19:11:30.066Z","dateUpdated":"2026-08-14T16:38:42.016Z","assignerShortName":"elastic","assignerOrgId":"271b6943-45a9-4f3a-ab4e-976f3fa05b5a","dateReserved":"2026-08-10T11:17:45.103Z"},"containers":{"cna":{"title":"Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions","descriptions":[{"lang":"en","value":"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).
