All in One Music Player <= 1.3.1 - Authenticated (Contributor+) Path Traversal via theme Parameter

The All in One Music Player plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.1 via the 'theme' parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of files on the server, which can contain sensitive information.
