Upgrade Twisted to version 24.7.0rc1 or higher.
Overview
Twisted is an event-based network programming and multi-protocol integration framework.
Affected versions of this package are vulnerable to HTTP Response Smuggling. When sending multiple HTTP/1.1 requests in one TCP segment, twisted.web does not guarantee the response order. An attacker in control of an endpoint can manipulate a different user's second response to a pipelined chunked request by delaying the response to their own request. Information disclosure across sessions may also be possible for reverse proxy servers using pooled connections.
Workaround
This vulnerability can be avoided by enforcing HTTP/2, as it is only vulnerable for HTTP/1.x traffic.
