Overview
org.elasticsearch:elasticsearch is a Distributed, RESTful Search Engine.
Affected versions of this package are vulnerable to Uncontrolled Recursion via the aggregation processing of the search API. An attacker can exhaust server resources and cause node termination by submitting a specially crafted request with deeply nested aggregation definitions. This is only exploitable if the attacker is an authenticated user with read access to at least one index.
