Overview
Affected versions of this package are vulnerable to Missing Authorization via the fs.realpathSync.native() function. An attacker running malicious code within a restricted Node.js environment (where --allow-fs-read is intentionally limited) can exploit this missing check to verify file existence, resolve symlink targets, and enumerate paths outside of the permitted directories, leading to unauthorized information disclosure.
