How to fix?

Upgrade Microsoft.ChakraCore to version 1.11.9 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). The Chakra scripting engine improperly 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 and then escalate privileges from there.
