Quick assessment

Affected
n/a vm2
Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

vm2是捷克Patrik Simek个人开发者的一个 Node.js 的高级虚拟机/沙盒。以使用列入白名单的 Node 内置模块运行不受信任的代码。 vm2 3.6.11之前版本存在安全漏洞，该漏洞源于通过无限递归达到堆栈调用限制，有可能从主机而不是"沙盒"上下文触发RangeError异常，然后使用返回的对象来引用运行脚本主机代码的mainModule属性，从而允许它生成一个child_process并执行任意代码。

Vulnerability Title
Sandbox Bypass
Source: CVE Program / CVE List V5
Vulnerability 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.
