How to fix?
Upgrade Microsoft.ChakraCore to version 1.11.2 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 and gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability 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.
