{"id":"CVE-2026-72671","state":"PUBLISHED","title":"Missing Authorization in Kibana Leading to Unauthorized Modification of Machine Learning Trained Model Space Assignments","description":"A Kibana Machine Learning capability that removes a saved object from the current space accepts machine learning trained models as a target, but it verifies only the privileges that apply to anomaly detection jobs and data frame analytics jobs. A user whose role grants create anomaly detection jobs and data frame analytics jobs without the trained model privilege can therefore remove a trained model from a space. The model itself is not deleted and remains available in its other spaces, and the change can be reversed by a suitably privileged user.","publishedAt":"2026-08-13T19:11:15.270Z","updatedAt":"2026-08-13T20:33:05.978Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"elastic"},"assigner":"elastic","products":["Elastic Kibana"],"affected":[{"vendor":"Elastic","product":"Kibana","defaultStatus":"unaffected","versions":[{"version":"8.0.0","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-2026-88/389525"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72671.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72671","state":"PUBLISHED","datePublished":"2026-08-13T19:11:15.270Z","dateUpdated":"2026-08-13T20:33:05.978Z","assignerShortName":"elastic","assignerOrgId":"271b6943-45a9-4f3a-ab4e-976f3fa05b5a","dateReserved":"2026-08-10T11:17:49.704Z"},"containers":{"cna":{"title":"Missing Authorization in Kibana Leading to Unauthorized Modification of Machine Learning Trained Model Space Assignments","descriptions":[{"lang":"en","value":"A Kibana Machine Learning capability that removes a saved object from the current space accepts machine learning trained models as a target, but it verifies only the privileges that apply to anomaly detection jobs and data frame analytics jobs.
