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 Advanced Post Block – Display Posts, Pages, or Custom Posts on Your Page plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the apbPosts() function hooked via an AJAX action in all versions up to, and including, 1.13.1. This makes it possible for unauthenticated attackers to retrieve all post data, including those that may be password protected.
