How to fix?

Upgrade Microsoft.ChakraCore to version 1.11.6 or higher.

Overview

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 scripting engine handles objects in memory in Microsoft Edge. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could 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. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
