NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:20/nodejs-packaging package and not the nodejs:20/nodejs-packaging package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

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.
