{"apiVersion":"1.0","identifier":"CVE-2026-72687","description":"A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single small request containing a forged opaque identifier. Elasticsearch decodes and deserializes the identifier before confirming that it was legitimately issued by the cluster, and a size value carried inside the identifier drives an allocation that is neither capped nor accounted for by the available memory-usage controls. The resulting out-of-memory condition is fatal and terminates the affected node process, resulting in a denial of service.","publishedAt":"2026-08-13T20:17:29","lastModifiedAt":"2026-08-28T15:32:26","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72687","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.0029,"riskScore":0.67,"affectedProduct":"Elasticsearch","affectedVersions":"unknown","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72687","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72687","en":"https://www.redsauce.net/en/cves/CVE-2026-72687","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72687","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72687","de":"https://www.redsauce.net/de/cves/CVE-2026-72687","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72687","el":"https://www.redsauce.net/el/cves/CVE-2026-72687"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72687"}}
