All push notification for WP <= 1.5.3 is vulnerable to CSRF to SQL Injection vulnerability

The All push notification for WP plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5.3. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to inject SQL queries via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
