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 User Shortcodes Plus plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.2 via the user_meta shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to retrieve potentially sensitive user meta.
