Grab & Save <= 1.0.4 - Cross-Site Request Forgery

Description

The Grab & Save plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.4. This is due to missing or incorrect nonce validation on the media_process() function. This makes it possible for unauthenticated attackers to upload images via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
