ChakraCore and Microsoft Edge in Windows 10 1703, 1709, and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how the scripting engine handles objects in memory. This could be exploited using write-AV when writing to a slot of a JavaScript null scope object.
