vm2 Custom Module Resolver Can Bypass the External Package Allowlist by Loading a Colliding Host Package

Summary vm2 is a sandbox library for isolating and executing untrusted JavaScript code inside a Node.js process. It can restrict access to built-in modules and external packages. When NodeVM enables an external allowlist together with a custom resolve callback, vm2 checks the requested package na...

vm2: vm.freeze()/vm.readonly() bypass via accessor descriptor

Summary Untrusted JavaScript running inside new VM.run / new NodeVM.run can bypass vm.freeze / vm.readonly and mutate a host object the embedder explicitly marked read-only - the documented contract is "prevent sandboxed scripts from adding, changing, or deleting properties". If the frozen host...

GHSA-8HR7-R645-PC6W vm2: NodeVM nesting guard accepts array-shaped require and permits host RCE

Summary The NodeVM constructor computes hasRealRequireConfig using typeof requireOpts === 'object' && requireOpts !== null, so require: bypasses the guard intended to reject nesting without an explicit require configuration. makeResolverFromLegacyOptions then destructures the array to undefined...

vm2: GHSA-m283-3h24-438v fix bypass leads to host RCE via call/apply indirection

Summary Untrusted JavaScript run by vm2 can escape the sandbox and execute arbitrary commands in the host Node.js process when an embedder-exposed host Promise rejects. This is an incomplete fix for GHSA-m283-3h24-438v: the advisory's capability-bearing rejection rebuild runs only through this...

vm2 allows a sandboxed plugin to execute native code through `node:sqlite`

Summary vm2 3.11.6 exposes Node.js's host node:sqlite module to NodeVM code when that builtin is allowed explicitly or through builtin: ''. The module is wrapped as read-only, but callable methods retain host-process authority. A sandboxed plugin can construct an in-memory database with extension...
