    Medium [CVE-2026-72678] Denial of Service via excessive memory allocation

    CVE-2026-72678Source published Source updated

    Elasticsearch does not validate a size value taken from a user-supplied input before that value is used to reserve memory for an internal data structure. An authenticated user holding only read privileges can submit a single small crafted request to a product API endpoint that causes the node to attempt an excessively large allocation. The resulting memory exhaustion raises a fatal error that terminates the Elasticsearch node process, causing a denial of service for the affected node and degrading cluster health. The defect is not volumetric, so a single request is sufficient regardless of the heap size configured on the target node. A flaw was found in Elasticsearch. An unvalidated allocation flaw exists in Elasticsearch's API request processing mechanisms. When handling user-supplied…
