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 Cookie Choice WordPress plugin through 1.1.0 is lacking any CSRF check when saving its options, and do not escape them when outputting them in attributes. As a result, an attacker could make a logged in admin change them to arbitrary values including XSS payloads via a CSRF attack.
