Django URL Redirection to Untrusted Site (Open Redirect) Vulnerability - CVE-2017-7233

Django 1.10 before 1.10.7 1.9 before 1.9.13 and 1.8 before 1.8.18 relies on user input in some cases to redirect the user to an quoton successquot URL. The security check for these redirects (namely django.utils.http.is_safe_url()) considered some numeric URLs quotsafequot when they shouldn39t be aka an open redirect vulnerability. 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.
