{"id":"CVE-2019-7611","aliases":["GHSA-fj32-6v7m-57pg"],"url":"https://o3.security/vulnerability/CVE-2019-7611","summary":"Improper Access Control in Elasticsearch","details":"A permission issue was found in Elasticsearch versions before 5.6.15 and 6.6.1 when Field Level Security and Document Level Security are disabled and the _aliases, _shrink, or _split endpoints are used . If the elasticsearch.yml file has xpack.security.dls_fls.enabled set to false, certain permission checks are skipped when users perform one of the actions mentioned above, to make existing data available under a new index/alias name. This could result in an attacker gaining additional permissions against a restricted index.","published":"2019-03-25T19:29:02.257Z","modified":"2026-07-08T19:51:10.469372Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.elasticsearch:elasticsearch","fixedVersion":"5.6.15"},{"ecosystem":"Maven","name":"org.elasticsearch:elasticsearch","fixedVersion":"6.6.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://discuss.elastic.co/t/elastic-stack-6-6-1-and-5-6-15-security-update/169077"},{"type":"ADVISORY","url":"https://www.elastic.co/community/security"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T19:51:10.469372Z"}}
