The Insight Core WordPress plugin through 1.0 does not have any authorisation and CSRF checks in the insight_customizer_options_import (available to any authenticated user) does not validate user input before passing it to unserialize() nor sanitise and escape it before outputting it in the response. As a result it could allow users with a role as low as Subscriber to perform PHP Object Injection as well as Stored Cross-Site Scripting attacks
