CVE-2020-7238: Inconsistent Interpretation of HTTP Requests (HTTP Request Smuggling)

January 27, 2020 (updated May 27, 2021)

Netty allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.
