Download Theme <= 1.0.9 - Cross-Site Request Forgery via dtwap_download()

The Download Theme plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.9. This is due to missing or incorrect nonce validation on the dtwap_download() function. This makes it possible for unauthenticated attackers to download theme zips on others computers, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
