Doc Text:
A flaw was found in Node.js 14.x, in versions before 14.11, where it is vulnerable to a denial of service caused by delayed requests. When used as an edge server, this flaw allows an attacker to initiate a large number of HTTP requests, causing resource exhaustion and leaving the service unable to accept new connections. The highest threat from this vulnerability is to system availability.

Description Doran Moppert 2020-09-16 01:16:31 UTC 
Node.js 14.x versions prior to 14.11 are vulnerable to a denial of service condition based on delayed requests.  When used as an edge server, an attacker can initiate but not complete a large number of HTTP requests causing resource exhaustion and rendering the server unable to accept new connections.

In 14.11 a new option "http.Server.requestTimeout" is introduced to mitigate this vulnerability.
