Descriptions
Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer` `Uint8Array` objects.
This is distinct from CVE-2023-32004 which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`.
Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
Varias funciones `node:fs` permiten especificar rutas como cadenas u objetos `Uint8Array`. En entornos Node.js, la clase `Buffer` extiende la clase `Uint8Array`. Node.js evita el path traversal a través de cadenas (ver CVE-2023-30584) y objetos `Buffer` (ver CVE-2023-32004), pero no a través de objetos `Uint8Array` que no son `Buffer`. Esto es distinto de CVE-2023-32004, que solo se refería a objetos "Buffer". Sin embargo, la vulnerabilidad sigue el mismo patrón al usar "Uint8Array" en lugar de "Buffer". Tenga en cuenta que en el momento en que se emitió este CVE, el modelo de permiso es una característica experimental de Node.js.
