How to fix?

Upgrade Twisted to version 20.3.0 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 due to missing checks when requests with modified headers are sent. An attacker could exploit this vulnerability by using the following request smuggling techniques:

  1. Sending Requests with multiple Content-Length headers
  2. Sending Requests with a Content-Length header and a Transfer-Encoding header
  3. Sending Requests whose Transfer-Encoding header has a value other than chunked and identity
