DX-Watermark <= 1.0.4 - Cross-Site Request Forgery

Description

The DX-Watermark 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. This makes it possible for unauthenticated attackers to upload arbitrary files and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
