CVE-2023-46137

Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP r

Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline.

Version 23.10.0rc1 contains a patch for this issue.
