vm2 Sandbox Access to Host Buffer.alloc Allows timeout Bypass Resulting in Memory Exhaustion

Summary 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 host memory and crash the process with a FATAL ERROR:...

vm2 has a Sandbox Escape via Promise Constructor Unhandled Rejection (Process Crash DoS)

Summary 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 v3.10.2 only sanitized the onRejected callback in .then and...

Uncaught Exception

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 Uncaught Exception through the Promise constructor when an unhandled rejection propagates from the sandboxed environment to the host...

GHSA-947F-4V7F-X2V8 vm2 has a NodeVM builtin allowlist bypass via `module` builtin's `Module._load` that allows sandbox escape

Summary 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 bypassing vm2's builtin restriction. This allows sandboxed co...

GHSA-VWRP-X96C-MHWQ vm2: Mutable Proxies for Host Intrinsic Prototypes Allows Sandbox Escape

Summary 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 JavaScript running in a default VM or inherited NodeVM mutate...
