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.
