Description

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-r273-hxvj-fxhp. This link is maintained to preserve external references.

Original Description

vm2 is a sandbox for running untrusted Node.js code. In versions <= 3.11.7, NodeVM exposes the host util module to the sandbox as an unfiltered shallow copy (Object.assign({}, util) in defaultBuiltinLoaderUtil), and the deprecated sys builtin (an alias of host util) is exposed through the generic builtin loader. 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, including absolute file paths, function names, and line numbers for vm2 bridge internals and the embedding application's entrypoint. This bypasses the host-frame redaction introduced for GHSA-v27g-jcqj-v8rw, which only applies to the Error.prepareStackTrace formatting channel. The issue is fixed in vm2 3.11.8.

Weakness

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.

How to prevent it
  • Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
