Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to denial of service via Serialized Data with Nested Payloads (CAPEC-230). An unauthenticated attacker with network access to the remote cluster server interface of a node can send a specially crafted request that causes the node to terminate. No credentials are required. The attacker can repeat the request against each reachable node.
