XStore Core <= 5.3.5 - Authenticated (Subscriber+) Limited Arbitrary File Download

Description

The et-core-plugin plugin for WordPress is vulnerable to arbitrary file downloads in all versions up to, and including, 5.3.5. This is due to the plugin not properly restricting which files can be downloaded. This makes it possible for authenticated attackers, with subscriber-level access and above, to download arbitrary files that may contain sensitive information like wp-config.php.
