NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:24/v8-13.6-devel package and not the nodejs:24/v8-13.6-devel package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync() without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered fs.realpathSync.native().

As a result, code running under --permission with restricted --allow-fs-read can still use fs.realpathSync() to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.

This vulnerability affects Node.js 26.x, 24.x, and 22.x.
