How to fix?

Upgrade Microsoft.ChakraCore to version 1.11.3 or higher.

Overview

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

Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. This may cause the memory to be corrupted so an attacker could execute arbitrary code in the context of the current user.
