How to fix?

There is no fixed version for io.netty:netty.

Overview

io.netty:netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients.

Affected versions of this package are vulnerable to HTTP Request Smuggling. Netty mishandles whitespace before the colon in HTTP headers such as a Transfer-Encoding : chunked line. This can lead to HTTP request smuggling where an attacker can bypass security controls, gain unauthorized access to sensitive data, and directly compromise other application users.
