• EPSS: 1.3% probability of exploitation in the next 30 days

• Weakness: CWE-674

Description

This affects the package vm2 before 3.6.11. It is possible to trigger a RangeError exception from the host rather than the "sandboxed" context by reaching the stack call limit with an infinite recursion. The returned object is then used to reference the mainModule property of the host code running the script allowing it to spawn a child_process and execute arbitrary code.

Affected products

• patriksimek vm2: before 3.6.11 — fixed in 3.6.11

How to fix

Upgrade to a fixed version: patriksimek vm2 3.6.11. Check the vendor advisory for mitigations.
