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 and NodeVM configurations are affected without requiring special options.\n\n## PoC\n\nA default-configured `VM` runs attacker-supplied code. Calling `eval` with deliberately malformed source makes the host-side source transformer throw a `SyntaxError`; reading `.stack` on the caught error exposes the host call stack to the sandbox.\n\n```js\nconst { VM } = require(\"vm2\");\nconsole.log(new VM().run(`\n  var s; try { eval(\"@@@ catch\") } catch (e) { s = e.stack }\n  s;\n`));\n```\n\n### Observed output\n\n```text\nSyntaxError: Unexpected character '@'\n    at makeNiceSyntaxError (.../lib/transformer.js:41:16)\n    at transformer (.../lib/transformer.js:116:8)\n    at Object.transformAndCheck (.../lib/vm.js:76:14)\n    at Object.apply (.../lib/setup-sandbox.js:2585:16)\n    at VM.run (.../lib/vm.js:529:16)\n```\n\nThe stack string returned to the sandbox contains absolute host paths for `lib/transformer.js`, `lib/vm.js`, `lib/setup-sandbox.js`, Node internals, and the embedding application's own source file.\n\n## Impact\n\nSandboxed code running under the default `new VM()` or `new NodeVM()` configuration can read absolute filesystem paths of the embedding application's source tree plus host function names, bypassing the host-path redaction added for GHSA-v27g-jcqj-v8rw. On a multi-tenant code-runner this discloses deployment layout such as `/home/app/...` or `/var/task/...`, useful for fingerprinting and for chaining into further attacks. The bridge forwards `.stack` reads to the host-realm formatter (`lib/bridge.js:1482`), so the sandbox-side stack redaction never runs; the leak does not require special configuration and persists when string eval is disabled, because the host-side transformer throws before eval is handled.
