CVE-2024-21896

The permission model protects itself against path traversal attacks by
calling path.resolve() on any paths given by the user. If the path is to be
treated as a Buffer, the implementation uses Buffer.from() to obtain a
Buffer from the result of path.resolve(). By monkey-patching Buffer
internals, namely, Buffer.prototype.utf8Write, the application can modify
the result of path.resolve(), which leads to a path traversal
vulnerability. This vulnerability affects all users using the experimental
permission model in Node.js 20 and Node.js 21. Please note that at the time
this CVE was issued, the permission model is an experimental feature of
Node.js.
