{"id":"CVE-2026-102404","summary":"Uncontrolled Resource Consumption in Elasticsearch Leading to Denial of Service","details":"Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). A low-privileged authenticated user can submit a specially crafted query that causes uncontrolled memory growth in the query processing engine, resulting in an out-of-memory condition that terminates the Elasticsearch node. The condition can be triggered repeatedly, including by queries embedded in shared resources, causing persistent cluster unavailability.","aliases":["BIT-elasticsearch-2026-102404"],"modified":"2026-10-15T02:48:04.467893014Z","published":"2026-10-06T19:31:34.716Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102404.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"8.0.0"},{"last_affected":"8.19.22"},{"introduced":"9.0.0"},{"last_affected":"9.4.7"},{"introduced":"9.5.0"},{"last_affected":"9.5.4"}]}],"cna_assigner":"elastic","cwe_ids":["CWE-400"]},"references":[{"type":"WEB","url":"https://discuss.elastic.co/t/elasticsearch-8-19-23-9-4-8-9-5-5-security-update-esa-2026-185/390859"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102404.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102404"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/elastic/elasticsearch","events":[{"introduced":"1b6a7ece17463df5ff54a3e1302d825889aa1161"},{"fixed":"6940e499f8a38841809b8e295a20c6421c95d9e4"},{"introduced":"112859b85d50de2a7e63f73c8fc70b99eea24291"},{"fixed":"c042abbb0eaaaa61b49beef21d517468861a4db2"},{"introduced":"8d4246a64bc255212407b1b313fe402391299c88"},{"fixed":"48acba663b09e70b115dd879329141506c377890"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:elastic:elasticsearch:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.19.23"},{"introduced":"9.0.0"},{"fixed":"9.4.8"},{"introduced":"9.5.0"},{"fixed":"9.5.5"}]}}],"versions":["v9.5.4","v9.5.3","v9.5.2","v9.5.1","v9.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-102404.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
