{"id":"BIT-elk-2026-72674","summary":"Allocation of Resources Without Limits or Throttling in Kibana Leading to Denial of Service","details":"Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). A user-supplied list of document fields accepted by the Kibana Playground for RAG feature was neither bounded in length nor de-duplicated before it was used to assemble the response for each matching document. A single crafted request could therefore make Kibana build a response far larger than the data it was derived from, and the resulting processing and memory pressure exhausts the resources of the Kibana instance.","aliases":["BIT-kibana-2026-72674","CVE-2026-72674"],"modified":"2026-09-08T08:47:06.697918902Z","published":"2026-08-19T08:40:44.901Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:elasticsearch:kibana:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"ADVISORY","url":"https://discuss.elastic.co/t/kibana-9-3-8-9-4-4-security-update-esa-2026-91/389533"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72674"}],"affected":[{"package":{"name":"elk","ecosystem":"Bitnami","purl":"pkg:bitnami/elk"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.3.0"},{"fixed":"9.3.8"},{"introduced":"9.4.0"},{"fixed":"9.4.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/elk/BIT-elk-2026-72674.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"}
