CVE-2023-39332 is a cyber vulnerability that affects various `node:fs` functions in Node.js environments. It allows paths to be specified as either strings or `Uint8Array` objects, which can be exploited for path traversal attacks. While Node.js prevents path traversal through strings and `Buffer` objects, it does not provide protection for non-`Buffer` `Uint8Array` objects. The vulnerability is similar to CVE-2023-32004, which only applies to `Buffer` objects. At the time this CVE was issued, the permission model of Node.js was still an experimental feature. This vulnerability has a high severity rating with a base score of 9.8 and poses a potential danger to organizations as it can be exploited remotely without user interaction, leading to high impacts on integrity and confidentiality.
