vm2 is a sandbox that can run untrusted code with Node's built-in modules. In versions 3.9.17 and lower of vm2 it was possible to get a read-write reference to the node "inspect" method and edit options for "console.log". As a result a threat actor can edit options for the "console.log" command. This vulnerability was patched in the release of version "3.9.18" of "vm2". Users are advised to upgrade. Users unable to upgrade may make the "inspect" method readonly with "vm.readonly(inspect)" after creating a vm.
