The Sandbox plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the export_download action in all versions up to, and including, 0.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to download an entire copy of a sandbox environment which can contain sensitive information like the wp-config.php file.
