Sandbox Escape

vm2 is vulnerable to Sandbox Escape. The vulnerability is due to incomplete protection of dangerous cross-realm symbols in setup-sandbox.js and missing validation in the bridge's set, defineProperty, and deleteProperty traps. This allows sandboxed code to obtain and manipulate real cross-realm...

CVE-2026-44003

A flaw was found in vm2 before 3.11.0. A code transformer fast-path skips AST analysis when catch, import, and async are absent, allowing direct access to VM2INTERNALSTATEDONOTUSEORPROGRAMWILLFAIL and internal security functions handleException, wrapWith, import. Fixed in 3.11.0...

CVE-2026-44000

A flaw was found in vm2 before 3.11.0. Host-side Promises that resolve to host objects deliver values to sandbox .then callbacks without cross-realm conversion ensureThis instead of from/proxy wrapping, allowing sandbox code to interact with host objects directly. Fixed in 3.11.0...

CVE-2026-43997

A flaw was found in vm2 before 3.11.0, a Node.js sandbox library. Sandboxed code can obtain the host Object e.g. via HostObject.getOwnPropertySymbols and Symbolnodejs.util.inspect.custom, bypassing isolation and enabling arbitrary code execution on the host...

CVE-2026-45411

A flaw was found in vm2 before 3.11.3. Host exceptions can be caught from sandbox code using yield inside an async generator; closing the generator with return awaits the value and passes host exceptions back into the sandbox iterator, enabling escape and arbitrary host command execution. Fixed i...

CVE-2026-44005

A flaw was found in vm2 3.9.6 through 3.10.5. The VM bridge exposes mutable proxies for host intrinsic prototypes and forwards sandbox writes via otherReflectSet/otherReflectDefineProperty, allowing mutation of host Object.prototype, Array.prototype, and Function.prototype from inside the sandbox...

CVE-2026-44009

A flaw was found in vm2 before 3.11.2. A sandbox escape vulnerability allows remote attackers to execute arbitrary code on the host system by breaking vm2 isolation. Fixed in 3.11.2...

CVE-2026-44007

A flaw was found in vm2 before 3.11.1. With nesting: true, sandbox code can require'vm2' regardless of outer require settings including require: false, spawn an inner NodeVM with unrestricted require, and execute arbitrary OS commands on the host. Fixed in 3.11.1...

CVE-2026-44008

A flaw was found in vm2 before 3.11.2. The neutralizeArraySpeciesBatch method can invoke host-side getters on array prototypes, exposing host objects and the host Function into the sandbox for escape and arbitrary command execution. Fixed in 3.11.2...

CVE-2026-44006

A flaw was found in vm2 before 3.11.0. Sandboxed code can reach BaseHandler.getPrototypeOf to obtain arbitrary prototypes, enabling sandbox escape and arbitrary code execution. Fixed in 3.11.0...

Incomplete List of Disallowed Inputs

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the NodeVM builtin allowlist in lib/builtin.js. An attacker can read host-process state by supplying a sandb...
