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 Post WordPress Plugin WordPress plugin through 2.8.4 does not validate an attribute of one of its shortcode, which could allow users with a role as low as contributor to add a malicious shortcode to a page/post, which will redirect users to an arbitrary domain.
