Overview

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

Affected versions of this package are vulnerable to HTTP Request Splitting. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.
