Node.js monitoring with Datadog APM and distributed tracing

This Datadog security advisory details a denial-of-service (DoS) vulnerability in their Node.js APM integration stemming from excessive memory consumption when handling large request headers. The vulnerability could potentially crash Node.js applications. Datadog has released a fix in their APM integration (version 6.12.0 and later) which limits header size, and recommends users upgrade immediately to mitigate the risk.
