WP Category Post List Widget <= 2.0.3 - Cross-Site Request Forgery via gen_set_page

Description

The WP Category Post List Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.3. This is due to missing or incorrect nonce validation on the 'gen_set_page' function. This makes it possible for unauthenticated attackers to modify the plugin's options via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
