CVE-2014-3730: The django.util.http.is_safe_url function in Django 1.4 before 1.4.13, 1.5 before 1.5.8, 1.6 before 1.6.5,...

Security readout for executives and security teams

CVE-2014-3730 is an open redirect flaw in older Django releases. If an application trusted Django's URL safety check for redirects, an attacker could cause users to be sent to an unintended external site. The main business risk is phishing, credential capture, and trust abuse rather than direct server compromise. Exposure is likely limited to applications running the affected Django versions and using is_safe_url to validate user-controlled redirect destinations, such as return or next URLs. Prioritize remediation for internet-facing Django applications, especially those handling login or account workflows. This is usually not a direct takeover bug, but it can enable convincing phishing through trusted domains. Mitigation focus: Upgrade Django to a fixed release named in the CVE or later supported version.; Check vendor advisories for distribution-specific patched Django packages.; Review login, logout, invitation, and return-url flows using user-supplied redirect targets..
