How to fix?

Upgrade Microsoft.ChakraCore to version 1.7.8 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 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 and could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system and may be able to install programs; view, change, or delete data; or create new accounts with full user rights.
