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 WP Show Posts plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on multiple AJAX functions in all versions up to, and including, 1.1.5. This makes it possible for authenticated attackers, with subscriber access and above, to view arbitrary post metadata, list posts, and view terms and taxonomies.

The WP Show Posts plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.1.4 via the wpsp_display function. This makes it possible for authenticated attackers with contributor access and above to view the contents of draft, trash, future, private and pending posts and pages.

The WP Show Posts WordPress plugin before 1.1.4 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.
