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 WP Extra File Types WordPress plugin before 0.5.1 does not have CSRF check when saving its settings, nor sanitise and escape some of them, which could allow attackers to make a logged in admin change them and perform Cross-Site Scripting attacks
