This can lead to a Denial of Service (DoS) by consuming significant system resources, making the service unavailable to legitimate users.

This is an Important denial-of-service flaw in jackson-databind, affecting services that process deeply nested JSON data. Exploitation occurs when a service reads JSON as JsonNode and subsequently writes it back using JsonNode.toString(), leading to excessive resource consumption and potential service unavailability.
