CVE-2017-11801
ChakraCore allows an attacker to execute arbitrary code in the context of the current user, due to how the ChakraCore scripting engine handles objects in memory, aka "Scripting Engine Information Disclosure Vulnerability".
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
