The security check for these redirects (namely `django.utils.http.is_safe_url()`) considered some URLs with basic authentication credentials \"safe\" when they shouldn\u0027t be. For example, a URL like `http://mysite.example.com\\@attacker.com` would be considered safe if the request\u0027s host is `http://mysite.example.com`, but redirecting to this URL sends the user to `attacker.com`. Also, if a developer relies on `is_safe_url()` to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack.",
