CVE-2026-45411 vm2: Sandbox Breakout Using Async Generator

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.3, it is possible to catch a host exception using the yield expression inside an async generator. When the generator is closed using the return function, the value is awaited on and exceptions thrown in the then call will be caught by th...

CVE-2026-44009

vm2 (Node.js sandbox) contains a sandbox-breakout vulnerability: CVE-2026-44009, triggered by a null-proto exception in handleException, can let an attacker access the host Function and run arbitrary code, enabling remote-code-execution within the host. Affected: versions ≤ 3.11.1; patched in 3.1...

CVE-2026-44008 vm2: Snabox breakout via `neutralizeArraySpeciesBatch`

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-2026-44008

CVE-2026-44008 describes a vm2 sandbox escape in the Node.js vm2 library. Before version 3.11.2, the method neutralizeArraySpeciesBatch could interact with objects from the outside and, via a getter on Array.prototype, expose host objects to the sandbox, allowing an attacker to access the host Fu...

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...

CVE-2026-44007

vm2 contains a vulnerability where creating a NodeVM with nesting: true allows sandbox code to bypass outer VM restrictions (e.g., require: false) and construct an inner NodeVM with unrestricted require settings to execute host commands. Affected: vm2 versions up to 3.11.0 (and prior to 3.11.1). ...

CVE-2026-44006 vm2: Sandbox Escape

CVE-2026-44004 vm2: Host Process OOM DoS via Buffer.alloc (Timeout Bypass)

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-2026-44004

CVE-2026-44004 affects vm2, an open‑source VM/sandbox for Node.js. Before version 3.11.0, sandboxed code can call Buffer.alloc() with any size, allocating host-heap memory directly via a synchronous C++ call; vm2’s timeout cannot interrupt such calls. A single request can exhaust memory and crash...
