## Affected

- ninjateam FastDup – Fastest WordPress Migration & Duplicator: through 2.7

## Description

The FastDup – Fastest WordPress Migration & Duplicator plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.7 via the 'dir_path' parameter in the 'njt-fastdup/v1/template/directory-tree' REST API endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary directories on the server, which can contain sensitive information.
