GHSA-3VGF-8M4Q-Q4QR vm2: Default VM can mutate host TypedArray and ArrayBuffer intrinsics after the host-prototype pollution fix

Summary vm2's current host-intrinsic prototype protection is incomplete. The fix for GHSA-vwrp-x96c-mhwq blocks sandbox writes into classic host intrinsics such as Object.prototype, Array.prototype, and Function.prototype, but current head still lets sandbox code in a default VM reach and mutate...

vm2 sandbox escape to host RCE via revisited host-wrapped AggregateError bypassing Error sanitization cycle short-circuit

Summary vm2 3.11.6 this fork's latest release contains an incomplete-fix bypass of the Error.cause host-reference sanitization added in GHSA-m283-3h24-438v commit 7e3faaf. Sandbox code that catches a host-wrapped AggregateError which is revisited within a single handleException traversal...

GHSA-R273-HXVJ-FXHP vm2: util.getCallSites() bypasses GHSA-v27g-jcqj-v8rw host-frame redaction, leaks host call stack

Summary NodeVM exposes the host util module to the sandbox through an unfiltered shallow copy Object.assign, util. On Node.js = 22.9 this hands sandboxed code util.getCallSites, a programmatic stack-introspection API that returns the host process's full call stack — absolute file paths, function...

vm2 leaks absolute host filesystem paths to sandbox code via error stack formatting

Summary Attacker-controlled code can trigger a host-realm syntax error and read its stack through the vm2 bridge. Host-realm stack formatting bypasses the sandbox-side redaction, so the returned value exposes absolute paths from vm2, Node.js internals, and the embedding application. Default VM an...

vm2: timeout Option Bypass via FinalizationRegistry Cleanup Callback (Unbounded Host Event-Loop Block)

Vulnerability Summary vm2's VM timeout option is documented and relied upon as the mechanism that bounds how long sandboxed code may execute. In the current implementation, the timeout only wraps the single synchronous call to VMrun via doWithTimeout → this.runScriptscript in lib/vm.js. It does...

vm2: NodeVM `require.external` without an explicit `require.root` grants unrestricted host filesystem access and full RCE

Summary NodeVM's require.external option lets sandboxed code require local files and npm packages. When require.external is enabled and require.root is not explicitly set to a path that excludes nodemodules, two defaults combine to fully defeat the sandbox: - require.root defaults to unrestricted...

vm2: Sandboxed code can read and write host-realm memory via Node's shared Buffer pool

Summary Sandboxed code is able to disclose host memory used by small allocations by Buffer.from, Buffer.concat. Details vm2 exposes Buffer object to sandboxed code by default. Small Buffer allocations for example, Buffer.allocUnsafe, Buffer.fromarray, Buffer.fromstring, and Buffer.concat use the...

GHSA-WJWH-QQVP-G4P4 vm2 sandbox escape via WebAssembly.compileStreaming Promise species bypass

Summary There is a sandbox escape in vm2 3.11.5 / current HEAD when it is used on Node.js 26. The issue is reachable from a default new VM sandbox. No NodeVM, require permission, host object injection, or intentionally unsafe configuration is required. The escape is a patch-bypass of the same...
