A flaw in Node.js Permission API can cause a file metadata to be modified even on a path that was set as read-only with e.g. `--allow-fs-read`. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.

A flaw was found in Node.js. The Permission API allows a local user to modify file metadata on paths that have been explicitly set as read-only. This can lead to unauthorized changes in file properties, impacting the integrity of the file system.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
