## Overview

A flaw was found in Datadog dd-trace-go, a Go client library. A remote, unauthenticated attacker can exploit this vulnerability by sending a request with a specially crafted baggage header containing an arbitrarily large number of key-value pairs or a very large single value. This can lead to unbounded CPU and memory consumption, resulting in a denial of service (DoS) against HTTP services that have baggage propagation enabled.
