CVE-2023-39332 [HIGH] CVE-2023-39332: Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects 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-2023-3200
