Export and Import Users and Customers <= 2.6.2 - Directory Traversal to Authenticated (Administrator+) Limited Arbitrary File Read via download_file Function

The Export and Import Users and Customers plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.6.2 via the download_file() function. This makes it possible for authenticated attackers, with Administrator-level access and above, to read the contents of arbitrary log files on the server, which can contain sensitive information.
