Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-0219 Jedediah Smith reported that the WSGI environ in Django does not distinguish between headers containing dashes and headers containing underscores. A remote attacker could use this flaw to spoof WSGI headers. CVE-2015-0220 Mikko Ohtamaa discovered that the django.util.http.is_safe_url function in Django does not properly handle leading whitespaces in user-supplied redirect URLs. A remote attacker could potentially use this flaw to perform a cross-site scripting attack.
