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 License Manager for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the showLicenseKey() and showAllLicenseKeys() functions in all versions up to, and including, 3.0.7. This makes it possible for authenticated attackers, with admin dashboard access (contributors by default due to WooCommerce) to view arbitrary decrypted license keys. The functions contain a referrer nonce check. However, these can be retrieved via the dashboard through the "license" JS variable.
