Any client that can reach the server can crash it with one trivial malformed request.\nRepeating this process keeps the service offline. \nThere is no loss of confidentiality or integrity. Only availability. Since HTTP/1.1 and HTTP/2 are served by default this affects effectively all deployments of the framework, unless shielded by third parties (e.g. reverse proxies like
