TL;DR

The NodeVM builtin denylist omits process and inspector/promises. Sandboxed code that may load those builtins can call process.getBuiltinModule('child_process') or Runtime.evaluate via the inspector protocol. That bypasses intended builtin restrictions and executes code in the host process. The fix adds these modules to the dangerous builtin blocklist in lib/builtin.js.

Who does this affect?

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