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-2026-44003 vm2: Transformer Fast-Path Bypass Exposes Internal State Variable

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, vm2's code transformer has a performance optimization that skips AST analysis when the code does not contain catch, import, or async keywords. This fast-path bypass allows sandboxed code to directly access the internal...

CVE-2026-44002

CVE-2026-44002 affects the vm2 sandbox for Node.js. Before 3.11.0, the CallSite wrapper blocks getThis() and getFunction() but allows getFileName() to reveal unsanitized host absolute paths. This enables sandboxed code to leak the host directory structure, library paths, and framework versions (v...

CVE-2026-44002 vm2: Host File Path Disclosure via Stack Trace Information Leak

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, vm2's CallSite wrapper class intended as a safe wrapper for V8's native CallSite blocks getThis and getFunction to prevent host object leakage, but allows getFileName to return unsanitized host absolute paths. Any sandboxed code can...

CVE-2026-44001 vm2: Sandbox Escape via Promise Constructor Unhandled Rejection (Process Crash DoS)

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, a sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 v3.10....

CVE-2026-44000 vm2: sandbox boundary bypass via host Promise resolution preserving host object identity

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-2026-44000

CVE-2026-44000 (vm2) : A sandbox boundary bypass in vm2 prior to version 3.11.0 allows host object identity to cross into the sandbox via host Promise resolution. When a host-side Promise resolves to a host object and is exposed to the sandbox, the value delivered to the sandbox .then() callback ...

CVE-2026-43999 vm2: NodeVM builtin allowlist bypass via `module` builtin's `Module._load` allows sandbox escape

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, NodeVM's builtin allowlist can be bypassed when the module builtin is allowed including via the '' wildcard. The module builtin exposes Node's Module.load, which loads any module by name directly in the host context, completely...

CVE-2026-43999

CVE-2026-43999 affects vm2’s NodeVM when the builtins allowlist is configured with a wildcard that includes the module builtin. Prior to version 3.11.0, the module builtin can bypass vm2’s allowlist via Module._load, because vm2 exposes the host’s Module object through a readonly proxy that still...

CVE-2026-43998 vm2: NodeVM require.root bypass via symlink traversal allows sandbox escape

vm2 is an open source vm/sandbox for Node.js. In 3.10.5, NodeVM's require.root path restriction can be bypassed using filesystem symlinks, allowing sandboxed code to load modules from outside the allowed root directory in host context. Because path validation uses path.resolve which does not...

CVE-2026-43997 vm2: Sandbox Escape

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, it is possible to obtain the host Object. There are various ways to use the host Object, to escape the sandbox, one example would be using HostObject.getOwnPropertySymbols to obtain Symbolnodejs.util.inspect.custom. This vulnerability...

CVE-2026-43997

CVE-2026-43997 affects the vm2 sandbox for Node.js. The vuln enables an attacker to obtain the host Object and escape the sandbox, potentially leading to arbitrary code execution (RCE). Affected versions were
