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.
node >= 22.23.3 <= 22.23.3node >= 24.22.0 <= 24.22.0node >= 26.12.0 <= 26.12.0Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
