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 (report 2038134), which only referred to Buffer
objects. However, the vulnerability follows the same pattern using Uint8Array
instead of Buffer
.Impacts:This vulnerability affects all users using the experimental permission model in Node.js 20.Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
