CVE-2018-0939
ChakraCore and Microsoft Edge in Windows 10 1703 and 1709 allow information disclosure, due to how the scripting engine handles objects in memory, aka "Scripting Engine Information Disclosure Vulnerability".
Does this matter?
Lower severity and a low EPSS score (5.50%). Track it; it rarely justifies an emergency change on its own.
