What is CVE-2019-5737?

Node.js versions prior to 6.17.0, 8.15.1, 10.15.2, and 11.10.1 are susceptible to a DoS attack. An attacker can exploit this by establishing HTTP or HTTPS connections in keep-alive mode and sending headers at a slow rate. This behavior harbors connections and their resources for an extended period, which can lead to service disruptions. Mitigation strategies include deploying load balancers or proxy layers to manage traffic more effectively. This vulnerability is related to a previous security issue (CVE-2018-12121) and affects all actively maintained Node.js release lines.
