vm2 is vulnerable to Protection Mechanism Failure

Medium Risk
This Affects:
vm2TL;DR
The code transformer’s fast path can be bypassed using with, internal state naming, and certain unicode-escaped identifier shapes. That exposes a privileged internal state name to guest-transformed code. Attackers use that exposure as a pivot into broader sandbox weaknesses. The transformer and identifier handling are hardened so internal state cannot be reached through these syntax tricks.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
