Description
The Broken Link Checker plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.4.14.1 due to missing nonce validation on the recheck action of the settings page, which ran before the settings form's nonce check. This makes it possible for unauthenticated attackers to truncate the plugin's link and link instance tables, discarding all accumulated scan results and forcing a full resynchronization, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
