CVE-2023-46137 Open this link in a new tabHow to fix?
Upgrade Twisted to version 23.10.0rc1 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.
Workaround
This vulnerability can be avoided by enforcing HTTP/2, as it is only vulnerable for HTTP/1.x traffic.
