Short explanation
A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync() without required read permission checks. CVE-2026-106073 is an incomplete fix for CVE-2026-21715, which only covered fs.realpathSync.native(). This vulnerability affects Node.js 26.x, 24.x, and 22.x.
Code running under permission constraints can still use fs.realpathSync() to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.
What should be done?
- Follow vendor advisories
- Review permission model configurations

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**.
