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 WooCommerce Multiple Free Gift plugin for WordPress is vulnerable to gift manipulation in all versions up to, and including, 1.2.3. This is due to plugin not enforcing server-side checks on the products that can be added as a gift. This makes it possible for unauthenticated attackers to add non-gift items to their cart as a gift.
