Note: Versions mentioned in the description apply only to the upstream elasticsearch-8 package and not the elasticsearch-8 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to denial of service via Exponential Data Expansion (CAPEC-197). An authenticated user may submit a specially crafted query to the ES|QL engine that causes exponential CPU consumption during query evaluation. Because the resource exhaustion persists beyond query completion, repeated requests can fully exhaust the available query worker resources, rendering ES|QL queries unavailable until the node is restarted.
