The Thumbnail Slider With Lightbox plugin for WordPress is vulnerable to Cross-Site Request Forgery in version 1.0. This is due to missing or incorrect nonce validation on the addedit functionality. This makes it possible for unauthenticated attackers to upload arbitrary files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
