Read More Excerpt Link <= 1.5 - Cross-Site Request Forgery

The Read More Excerpt Link plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.5. This is due to missing or incorrect nonce validation on the read_more_excerpt_link_menu_options function. This makes it possible for unauthenticated attackers to invoke this function and change plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
