vm2Duplicate 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This advisory has been withdrawn because it is a duplicate of GHSA-r273-hxvj-fxhp.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.
