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 Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 3.7.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.7.7. This is due to insufficient verification on the user being supplied during a Stripe checkout through the plugin. This allows unauthenticated attackers to log in as users who have orders, who are typically customers.

The Stripe Payment Plugin for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the eh_callback_handler function in versions up to, and including, 3.7.9. This makes it possible for unauthenticated attackers to modify the order status of arbitrary WooCommerce orders.
