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 Free Live Chat Support plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including 1.0.11. This is due to missing nonce protection on the livesupporti_settings() function found in the ~/livesupporti.php file. This makes it possible for unauthenticated attackers to inject malicious web scripts into the page, granted they can trick a site's administrator into performing an action such as clicking on a link.
