TL;DR

Attacker-controlled __proto__ assignments can mutate host prototypes through the vm2 bridge. That breaks isolation between the sandbox realm and the host JavaScript environment. Exploitation yields arbitrary code execution in the Node.js host process. The patch blocks host prototype mutation paths in sandbox setup and bridge code.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.

Background info

vm2 is vulnerable to Remote Code Execution (RCE) in versions 3.0.0 - 3.11.3.
