How to fix?

Upgrade vm2 to version 3.9.17 or higher.

Overview

vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules.

Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions due to allowing attackers to raise an unsanitized host exception inside handleException() which can be used to escape the sandbox and run arbitrary code in host context.
