vm2 is vulnerable to Prototype Pollution
100
Critical Risk
This Affects:
vm2TL;DR
Write traps on bridged objects can reach host intrinsic prototypes in a way that mutates objects the host runtime relies on. Guest-controlled writes become prototype pollution that crosses the sandbox boundary into host behavior. That breaks isolation assumptions about what guest mutations can affect. The fix blocks those write paths from polluting host intrinsics.
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 Prototype Pollution in versions 3.9.6 - 3.10.5.
