CyberRota Analysis
AI-GeneratedElasticsearch is vulnerable due to improper validation of user-supplied size values, allowing an authenticated user with read privileges to craft a request that triggers excessive memory allocation. This can lead to memory exhaustion, resulting in a denial of service that crashes the Elasticsearch node and impacts overall cluster health. Organizations using Elasticsearch should prioritize remediation to prevent potential disruptions in service.
Original NVD Description
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.
