Cross-site scripting (XSS) vulnerability in the dismissChangeRelatedObjectPopup function in contrib/admin/static/admin/js/admin/RelatedObjectLookups.js in Django before 1.8.14, 1.9.x before 1.9.8, and 1.10.x before 1.10rc1 allows remote attackers to inject arbitrary web script or HTML via vectors involving unsafe usage of Element.innerHTML.
The (1) contrib.sessions.backends.base.SessionBase.flush and (2) cache_db.SessionStore.flush functions in Django 1.7.x before 1.7.10, 1.4.x before 1.4.22, and possibly other versions create empty sessions in certain circumstances, which allows remote attackers to cause a denial of service (session store consumption) via unspecified vectors.
contrib.sessions.middleware.SessionMiddleware in Django 1.8.x before 1.8.4, 1.7.x before 1.7.10, 1.4.x before 1.4.22, and possibly other versions allows remote attackers to cause a denial of service (session store consumption or session record removal) via a large number of requests to contrib.auth.views.logout, which triggers the creation of an empty session record.
Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 uses an incorrect regular expression, which allows remote attackers to inject arbitrary headers and conduct HTTP response splitting attacks via a newline character in an (1) email message to the EmailValidator, a (2) URL to the URLValidator, or unspecified vectors to the (3) validate_ipv4_address or (4) validate_slug validator.
Cross-site scripting (XSS) vulnerability in the contents function in admin/helpers.py in Django before 1.7.6 and 1.8 before 1.8b2 allows remote attackers to inject arbitrary web script or HTML via a model attribute in ModelAdmin.readonly_fields, as demonstrated by a @property.
