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 Coupon Zen WordPress plugin before 1.0.6 does not have CSRF check when activating plugins, which could allow attackers to make logged in admins activate arbitrary plugins present on the blog via a CSRF attack
