Improper Isolation or Compartmentalization

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 Isolation or Compartmentalization through the NodeVM constructor in lib/nodevm.js. An attacker can run host commands when the VM is set up...

Symlink Attack

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 Symlink Attack via the isPathAllowed path check in lib/resolver-compat.js. An attacker can execute code outside the configured require.root by placin...

vm2 has a NodeVM require.root bypass via symlink traversal that allows sandbox escape

Summary 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 dereference symlinks but module loading uses Node's...

vm2 is Vulnerable to Host File Path Disclosure via Stack Trace Information Leak

Summary 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 extract the full directory structure, library paths, and...

Information Exposure

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 Information Exposure via the sandbox CallSite handling. An attacker can leak absolute host filesystem paths by causing error.stack or getEvalOrigin t...

vm2 Host Promise Resolution Preserves Object Identity Across Sandbox Boundary

Summary 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 sandbox .then callback preserves host identity. This...

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
