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 Frontend Registration – Contact Form 7 plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.1 due to insufficient restriction on the '_cf7frr_' post meta. This makes it possible for authenticated attackers, with editor-level access and above, to modify the default user role in the registration form settings.
