Overview

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

Affected versions of this package are vulnerable to HTTP Request Smuggling. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.
