How to fix?

Upgrade netius to version 1.17.58 or higher.

Overview

netius is a Python network library that can be used for the rapid creation of asynchronous non-blocking servers and clients.

Affected versions of this package are vulnerable to HTTP Request Smuggling. HTTP pipelining issues and request smuggling attacks might be possible due to incorrect Transfer encoding header parsing which could allow for CL:TE or TE:TE attacks.

By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other than their own.
