CVE-2026-44008

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.2, the new method neutralizeArraySpeciesBatch works with objects from the other side but can call into this side via getter on the array prototype exposing objects of the wrong side into the sandbox. This can be used to get host objects...

CVE-2026-44006

Improper Control of Dynamically-Managed Code Resources

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Improper Control of Dynamically-Managed Code Resources through the WebAssembly.promising and WebAssembly.Suspending JSPI APIs in...

vm2 has a CVE-2023-37903 patch bypass: nesting:true without explicit require still allows full RCE

Summary The fix for GHSA-8hg8-63c5-gwmx CVE-2023-37903 introduced a check in nodevm.js line 263 that blocks the combination nesting: true + require: false. However, the check uses strict equality options.require === false, which is trivially bypassed by omitting the require option entirely. When...

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 through Symbol.for handling in lib/setup-sandbox.js and the bridge write traps in lib/bridge.js. An attacker can...

Improper Validation of Array Index

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 Improper Validation of Array Index through the defaultSandboxPrepareStackTrace function in lib/setup-sandbox.js. An attacker can observe or rewrite...

Improper Control of Dynamically-Managed Code Resources

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 Improper Control of Dynamically-Managed Code Resources through the lib/bridge.js apply trap and thisEnsureThis proto-walk. An attacker can obtain hos...

CVE-2026-24120

A flaw was found in vm2, an open-source sandbox for Node.js. This vulnerability allows a remote attacker to bypass existing security controls, specifically the fix for CVE-2023-37466. By circumventing the sandbox, an attacker can execute arbitrary commands on the host system, leading to a complet...

CVE-2026-44004

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, sandboxed code can call Buffer.alloc with an arbitrary size to allocate memory directly on the host heap. Because Buffer.alloc is a synchronous C++ native call, vm2's timeout option cannot interrupt it. A single request can exhaust ho...

CVE-2026-44005

vm2 is an open source vm/sandbox for Node.js. From 3.9.6 to 3.10.5, vm2's bridge exposes mutable proxies for real host-realm intrinsic prototypes and then forwards sandbox writes into the underlying host objects with otherReflectSet and otherReflectDefineProperty, which lets attacker-controlled...

CVE-2026-44000

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox boundary violation in vm2 allows host object identity to cross into the sandbox through host Promise resolution. When a host-side Promise that resolves to a host object is exposed to the sandbox, the value delivered to the...

CVE-2026-45411

vm2 is a Node.js sandbox; prior to 3.11.3, an async generator yield* can cause host exceptions to escape the VM when the generator is closed with return, with exceptions from then being routed to the yield* iterator as the next value, enabling arbitrary host commands. This is fixed in 3.11.3. The...

CVE-2026-44007 vm2: nesting: true bypasses require: false, allowing sandbox escape to arbitrary OS command execution

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.1, when a NodeVM is created with nesting: true, sandbox code can unconditionally require'vm2' regardless of the outer VM's require configuration — including require: false. With access to vm2, the sandbox constructs a new inner NodeVM wi...
