What is CVE-2024-21891?

A vulnerability exists in Node.js due to its reliance on built-in utility functions to normalize paths provided to the node:fs system. This weakness allows for user-defined implementations to overwrite these functions, which can result in a bypass of the filesystem permission model through a path traversal attack. It impacts users utilizing the experimental permission model in Node.js versions 20 and 21. Given that the permission model is still experimental, this introduces significant risk for users who may not be fully aware of the implications of this vulnerability. For further insights, reference material can be found in security advisories.
