How to fix?

Upgrade Microsoft.ChakraCore to version 1.11.7 or higher.


Microsoft.ChakraCore is a core part of the Chakra Javascript engine that powers Microsoft Edge

Affected versions of this package are vulnerable to Information Exposure because the scripting engine does not properly handle objects in memory in Microsoft Edge. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.
