Description
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-46pr-c5wc-xffx. This link is maintained to preserve external references. ## Original Description vm2 3.11.3 through 3.11.6 exposes the host Node.js crypto module to a NodeVM sandbox when the crypto builtin is allowed. The module is presented via a recursive read-only proxy, but its callable exports still execute with host-process authority. Sandboxed JavaScript can therefore call crypto.setEngine() with a filesystem path to an attacker-supplied native library (for example, one bundled in an untrusted plugin package already written to disk); OpenSSL asks the operating-system dynamic loader to load the file, and the library's constructor executes native code in the host process before engine-symbol validation rejects it. Exploitation requires only the crypto builtin and does not require fs, process, module, child_process, worker_threads, vm, or inspector access, resulting in a sandbox escape and arbitrary native code execution. Fixed in 3.11.7.
