NVD Description

Note: Versions mentioned in the description apply only to the upstream twisted package and not the twisted package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

Twisted is an event-based framework for internet applications. Started with version 0.9.4, when the host header does not match a configured host twisted.web.vhost.NameVirtualHost will return a NoResource resource which renders the Host header unescaped into the 404 response allowing HTML and script injection. In practice this should be very difficult to exploit as being able to modify the Host header of a normal HTTP request implies that one is already in a privileged position. This issue was fixed in version 22.10.0rc1. There are no known workarounds.
