{"id":"BIT-elasticsearch-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":["CVE-2026-102404"],"modified":"2026-10-14T11:00:04.006127167Z","published":"2026-10-14T08:40:25.116Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:elastic:elasticsearch:*:*:*:*:*:maven:*:*"]},"references":[{"type":"ADVISORY","url":"https://discuss.elastic.co/t/elasticsearch-8-19-23-9-4-8-9-5-5-security-update-esa-2026-185/390859"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102404"}],"affected":[{"package":{"name":"elasticsearch","ecosystem":"Bitnami","purl":"pkg:bitnami/elasticsearch"},"ranges":[{"type":"SEMVER","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"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/elasticsearch/BIT-elasticsearch-2026-102404.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
