CVE-2024-1968: Scrapy leaks the authorization header on same-domain but cross-origin redirects

Since version 2.11.1, Scrapy drops the Authorization header when a request is redirected to a different domain. However, it keeps the header if the domain remains the same but the scheme (http/https) or the port change, all scenarios where the header should also be dropped.

In the context of a man-in-the-middle attack, this could be used to get access to the value of that Authorization header
