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 Radio Buttons for Taxonomies plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.5. This is due to missing or incorrect nonce validation on the save_single_term() function. This makes it possible for unauthenticated attackers to save terms via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
