For some query types, Elasticsearch can share cached query results between users who have field-level security restrictions and users who do not. A user restricted by field-level security can learn which documents match a value in a field that they cannot read. A restricted user can also cause users with full access to receive incomplete search results. Disclosure is only possible when a user with full access ran the same query on the same shard recently.","score":4.2,"severity":"medium","published":"2026-11-03T16:44:13.037Z","modified":"2026-11-03T17:30:13.952Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Elastic","name":"Elasticsearch","platforms":[],"versions":[{"version":"8.9.0","status":"affected","lessThanOrEqual":"8.19.23","versionType":"semver"},{"version":"9.0.0","status":"affected","lessThanOrEqual":"9.4.8","versionType":"semver"},{"version":"9.5.0","status":"affected","lessThanOrEqual":"9.5.5","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"elastic","url":"https://www.cve.org/CVERecord?id=CVE-2026-115710"}],"remediation":[],"references":["https://discuss.elastic.co/t/elasticsearch-8-19-24-9-4-9-9-5-6-security-update-esa-2026-210/391363"],"sources":[{"name":"CVE","id":"CVE-2026-115710","modified":"2026-11-03T17:30:13.952Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-115710"}],"assessments":[{"source":"elastic","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.2}],"sourceAffected":[],"observedAt":"2026-11-03T17:37:16.842Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T03:50:33.051Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-03T17:50:41.798Z","attemptedAt":"2026-11-03T17:50:41.798Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-03T17:50:39.635Z","attemptedAt":"2026-11-03T17:50:39.635Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-03T17:50:42.187Z","attemptedAt":"2026-11-03T17:50:42.187Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-03T17:50:41.652Z","attemptedAt":"2026-11-03T17:50:41.652Z"}],"evidence":[{"source":"NVD","id":"CVE-2026-115710","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115710","modified":"2026-11-03T17:17:55.897","score":4.2,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","checkedAt":"2026-11-03T17:50:41.798Z"}],"aiSummary":{"text":"Elasticsearch versions 8.9.0 to 8.19.23, 9.0.0 to 9.4.8, and 9.5.0 to 9.5.5 have a weakness where cached query results can be shared between users, potentially leading to information disclosure.
