Logaster Logo Generator <= 1.3 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Logaster Logo Generator plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3. This is due to missing nonce validation on the upload_logo_callback and delete_logo_callback functions. This makes it possible for unauthenticated attackers to delete arbitrary media files and upload arbitrary media files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
