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-2026-44006

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...

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...

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-2026-44004 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...

vm2 安全漏洞

vm2 is a high-level virtual machine/sandbox developed by Czech developer Patrik Simek. It runs untrusted code using Node’s built-in modules listed in the allowlist. Versions of vm2 prior to 3.11.0 have security vulnerabilities; these vulnerabilities stem from sandbox boundary violations. During...
