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) when the Control Flow Guard (CFG) could be bypassed. By itself, the CFG bypass vulnerability does not allow arbitrary code execution. However, an attacker could use the CFG bypass in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.
