Descripción
The Art Theme for WordPress is vulnerable to unauthorized access due a missing capability check on the 'arttheme_theme_option_restore' AJAX function in all versions up to, and including, 3.12.2.3. This makes it possible authenticated attackers, with subscriber-level above, delete theme option.
