Quick assessment
Affected
patriksimek vm2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
patriksimek vm2是patriksimek的沙箱。 Patrik Simek vm2 3.11.4之前版本存在权限许可和访问控制问题漏洞，该漏洞源于NodeVM通过require.builtin暴露进程级的内置可观察性模块（如diagnostics_channel、async_hooks和perf_hooks），这些模块未被危险内置黑名单阻止，沙箱代码可利用它们跨越vm2边界观察主机应用程序数据。

Vulnerability Title
vm2: NodeVM observability builtins leak host process and HTTP request data
Source: CVE Program / CVE List V5
Vulnerability Description
vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnostics_channel, async_hooks, and perf_hooks builtins are not blocked by the dangerous builtin denylist. These modules are process-wide, not sandbox-local. Sandboxed code can use them to observe host application data across the vm2 boundary. This issue has been patched in version 3.11.4.
