Filr - Secure Document Library < 1.2.2.1 - Subscriber+ AJAX Calls

The Filr WordPress plugin before 1.2.2.1 does not have authorisation check in two of its AJAX actions, allowing them to be called by any authenticated users, such as subscriber. They are are protected with a nonce, however the nonce is leaked on the dashboard. This could allow them to upload arbitrary HTML files as well as delete all files or arbitrary ones.
