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 Product Slider and Carousel with Category for WooCommerce WordPress plugin before 2.8 does not validate and escape one of its shortcode attributes, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attack.
