How to fix?

Upgrade Microsoft.ChakraCore to version 1.8.3 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 Remote Code Execution (RCE) due to the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. The vulnerability could cause memory corruption leading to arbitrary code execution in the context of the current user. An attacker 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.
