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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":4.2,"severity":"medium","source":"CNA: elastic","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793727013952,"publishedAt":1793724253037,"references":[{"source":"CNA: elastic","tags":[],"url":"https://discuss.elastic.co/t/elasticsearch-8-19-24-9-4-9-9-5-6-security-update-esa-2026-210/391363"}],"remediation":[],"revision":"ef4a268fd292ebcfdea312b03496aedbdd851fd69e7f707baafe157f7d2f7e9b","sources":[{"modifiedAt":1793727013952,"name":"CNA: elastic","retrievedAt":1793729337124,"url":"https://www.cve.org/CVERecord?id=CVE-2026-115710"}],"ssvc":{"assessedAt":1793727003351,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Use of Cache Containing Sensitive Information in Elasticsearch Leading to Information Disclosure","updatedAt":1793729337124}
