waitress is vulnerable HTTP request smuggling. The vulnerability exists because the library mishandled HTTP request header by not correctly parsing special whitespace characters in the Transfer-Encoding header, causing the parser to use Content-Length header instead to determine the HTTP message body size, ignoring the requests that are sent with the Transfer-Encoding:[0x0b]chunked. This vulnerability is related to CVE-2019-16786.
