The Easy Theme Options plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0. This is due to missing authorization checks in the eto_import_settings function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to import arbitrary plugin settings via the 'eto_import_settings' parameter.
