The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The Simple Sitemap – Create a Responsive HTML Sitemap plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.5.13. This is due to missing or incorrect nonce validation in the 'admin_notices' hook found in class-settings.php. This makes it possible for unauthenticated attackers to reset the plugin options to a default state via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
