Status: ModifiedMedium (6.5)—

Microsoft Edge in Microsoft Windows 10 1607, 1703, and Windows Server 2016 allows an attacker to force the browser to send data that would otherwise be restricted to a destination website of the attacker's choice, due to how Microsoft Edge handles redirect requests, aka "Microsoft Edge Security Feature Bypass Vulnerability". This CVE ID is unique from CVE-2017-11863 and CVE-2017-11874.
