What is CVE-2019-5739?

The vulnerability allows keep-alive HTTP and HTTPS connections to remain open and inactive for up to 2 minutes in Node.js versions prior to 6.17.0. This behavior poses a potential Denial of Service attack vector, allowing attackers to exploit resource consumption by keeping connections open without activity. Node.js 6.17.0 introduced a dedicated server.keepAliveTimeout feature, reducing the default inactivity timeout to 5 seconds, thus mitigating this issue.

Affected Version(s)

Node.js All versions prior to 6.17.0
