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 Photo Reviews Premium plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 1.3.13.2. This is due to the plugin not properly validating what user transient is being used in the login() function and not properly verifying the user's identity. This makes it possible for unauthenticated attackers to log in as user that has dismissed an admin notice in the past 30 days, which is often an administrator. Alternatively, a user can log in as any user with any transient that has a valid user_id as the value, though it would be more difficult to exploit this successfully.
