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 Restrict User Access – Ultimate Membership & Content Protection plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.5 via API. This makes it possible for unauthenticated attackers to obtain the contents of posts and pages via API.
