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 Authorize.net Payment Gateway For WooCommerce plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 8.0. This is due to the plugin not properly verifying the authenticity of the request that updates a orders payment status. This makes it possible for unauthenticated attackers to update order payment statuses to paid bypassing any payment.

plugin-fw/lib/yit-plugin-panel-wc.php in the YIT Plugin Framework through 3.3.8 for WordPress allows authenticated options changes.
