The Slick Social Share Buttons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'dcssb_ajax_update' function in versions up to, and including, 2.4.11. This makes it possible for authenticated attackers, with subscriber-level permissions or above to update the site options arbitrarily.
