How to fix?

Upgrade Twisted to version 22.4.0rc1 or higher.

Overview

Twisted is an event-based network programming and multi-protocol integration framework.

Affected versions of this package are vulnerable to HTTP Request Smuggling in the twisted.web.http module which makes non-conformant parsing and can lead to desync if requests pass through multiple HTTP parsers. Note: To be vulnerable, applications need to both use Twisted Web's HTTP server/proxy, along with some other HTTP server/proxy.
