How to fix?

Upgrade io.netty:netty-codec-http to version 4.1.44.Final or higher.

Overview

io.netty:netty-codec-http is a network application framework for rapid development of maintainable high performance protocol servers & clients.

Affected versions of this package are vulnerable to HTTP Request Smuggling due to the package mishandling Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header when using HTTP/1.1. This issue exists because of an incomplete fix for CVE-2019-16869.
