WP To Do <= 1.3.0 - Cross-Site Request Forgery via wptodo_manage()

Description The WP To Do plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.0. This is due to missing or incorrect nonce validation on the wptodo_manage() function. This makes it possible for unauthenticated attackers to add new todo items via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
