Preview Link Generator < 1.0.4 is vulnerable to Arbitrary Plugin Activation via CSRF vulnerability

The Preview Link Generator plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.3. This is due to missing or incorrect nonce validation on the plugin_activation function. This makes it possible for unauthenticated attackers to activate arbitrary installed plugins via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
