CWE ID 22

Summary

CVE-2023-39332 exposes a new path traversal vulnerability in Node.js, affecting various `node:fs` functions. Unlike previous vulnerabilities CVE-2023-30584 and CVE-2023-32004, this issue permits specifying paths as non-Buffer Uint8Array objects. Node.js currently prevents such traversal attacks on strings and Buffer objects, but not on other Uint8Array instances. This vulnerability follows a similar pattern as CVE-2023-32004, but involves the use of Uint8Array objects instead. At the time of this CVE disclosure, the permission model for Node.js is still considered experimental.
