CVE-2015-2317: The utils.http.is_safe_url function in Django before 1.4.20, 1.5.x, 1.6.x before 1.6.11, 1.7.x before 1.7.7...

Security readout for executives and security teams

CVE-2015-2317 is a Django URL-validation flaw that could let an attacker turn a supposedly safe redirect or link into browser-executed script. Business impact depends on whether old Django versions still power public web workflows that accept or reflect user-supplied URLs. Exposure is most likely in legacy Django applications using affected versions and relying on is_safe_url for redirect or URL trust decisions. Modern supported Django deployments are unlikely to be affected unless pinned to old packages or vendor backports missing this fix. Prioritize remediation for internet-facing legacy Django systems, especially login, account, and redirect flows. This is not KEV-listed in the provided data, but XSS in trusted web workflows can affect users and brand trust. Mitigation focus: Upgrade Django to a fixed upstream release or supported vendor-patched package.; Replace unsupported Django 1.5.x deployments with a supported fixed branch.; Prioritize public applications that process redirect targets or user-provided URLs..
