{"id":"BIT-elk-2026-72671","summary":"Missing Authorization in Kibana Leading to Unauthorized Modification of Machine Learning Trained Model Space Assignments","details":"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.","aliases":["BIT-kibana-2026-72671","CVE-2026-72671"],"modified":"2026-09-08T08:47:06.809808001Z","published":"2026-08-19T08:40:41.323Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:elasticsearch:kibana:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"ADVISORY","url":"https://discuss.elastic.co/t/kibana-8-19-20-and-9-4-5-security-update-esa-2026-88/389525"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72671"}],"affected":[{"package":{"name":"elk","ecosystem":"Bitnami","purl":"pkg:bitnami/elk"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.0.0"},{"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-2026-72671.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}],"schema_version":"1.9.0"}
