Descriptions

Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions, which can be overwitten with user-defined implementations leading to filesystem permission model bypass through path traversal attack.
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.

Node.js depende de múltiples funciones de utilidad integradas para normalizar las rutas proporcionadas a las funciones de node:fs, que pueden ser exageradas con implementaciones definidas por el usuario que conducen a la omisión del modelo de permisos del sistema de archivos mediante un ataque de path traversal. Esta vulnerabilidad afecta a todos los usuarios que utilizan el modelo de permiso experimental en Node.js 20 y Node.js 21. Tenga en cuenta que en el momento en que se emitió este CVE, el modelo de permiso es una característica experimental de Node.js.
