WP Import Export Lite < 3.9.33 - Authenticated Sensitive File Disclosure via Existing File Import Path Traversal

Description

The plugin does not validate a user-supplied file path before reading it and copying it into a publicly accessible directory, allowing any user whose role an administrator has granted the plugin's import permission to disclose sensitive files from the server, including files located outside the web root. The same code path also relaxes the file-system permissions of any path it is given, whether or not the copy succeeds.
