Uncontrolled Resource Consumption in Kibana Leading to Denial of Service

Assigner: elastic
Reserved: 27.05.2026 Published: 28.05.2026 Updated: 28.05.2026

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with viewer-level access can submit a request containing an oversized input value to an analytics collections management endpoint. Kibana will consume excessive CPU and memory resources while processing the request. This results in Kibana becoming unavailable to all users until the service is manually recovered.
