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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-284"],"references":["https://discuss.elastic.co/t/elastic-stack-6-6-1-and-5-6-15-security-update/169077","https://www.elastic.co/community/security","https://discuss.elastic.co/t/elastic-stack-6-6-1-and-5-6-15-security-update/169077","https://www.elastic.co/community/security"],"products":["elastic:elasticsearch"],"source":"nvd","synced_at":"2026-10-19T20:55:22.313337056+00:00"},"epss":{"cve":"CVE-2019-7611","score":0.02149,"percentile":0.82124,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-fj32-6v7m-57pg","url":"https://osv.dev/vulnerability/GHSA-fj32-6v7m-57pg","summary":"Improper Access Control in Elasticsearch","modified":"2023-11-08T04:01:38.856498Z","packages":[{"ecosystem":"Maven","name":"org.elasticsearch:elasticsearch","purl":"pkg:maven/org.elasticsearch/elasticsearch","ranges":["<5.6.15"],"fixed":["5.6.15"]},{"ecosystem":"Maven","name":"org.elasticsearch:elasticsearch","purl":"pkg:maven/org.elasticsearch/elasticsearch","ranges":[">=6.0.0 <6.6.1"],"fixed":["6.6.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
