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.
vm2 是一个用于在 Node.js 中运行不可信 JavaScript 的沙箱库。在版本 >= 3.10.0 且 <= 3.11.7 中，从宿主 realm（host realm）返回到沙箱的 Promise 未在桥接边界处被标记为已处理；只有那些在沙箱内部创建的 Promise 才会被包裹一个“吞掉拒绝”的处理程序（lib/setup-sandbox.js），并且桥接层仅当沙箱代码调用 .then/.catch/.finally 时，才会在宿主侧安装拒绝 sanitizer。 其结果是，运行在沙箱中的代码可以调

Vulnerability Title
vm2 3.10.0 through 3.11.5 Denial of Service via Host Promise
Source: CVE Program / CVE List V5
Vulnerability Description
vm2 is a sandbox library for running untrusted JavaScript in Node.js. In versions >= 3.10.0 and <= 3.11.7, Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary; only Promises created inside the sandbox are wrapped with a rejection-swallowing handler (lib/setup-sandbox.js), and the bridge only installs host-side rejection sanitizers when sandbox code calls .then/.catch/.finally. As a result, code running in the sandbox can invoke a host function that returns a rejected Promise (for example events.once() exposed via the NodeVM events builtin, or any embedder-provided Promise-returning API) and simply ignore the return value, leaving the host Promise unhandled so that Node.js's default unhandled-rejection behavior terminates the host process. This is an incomplete fix of GHSA-hw58-p9xv-2mjh. The issue is fixed in version 3.11.8.
