Description Adam Mariš 2016-02-24 09:06:49 UTC 
It was found that django.utils.http.is_safe_url() used as security check for redirecting URLs considered some malicious URLs with basic authentication credentials "safe", e.g. http://mysite.example.com\@attacker.com would be considered safe. Relying on is_safe_url() to provide safe redirect targets and putting such URLs into link can lead also to XSS attack.
