Five Star Business Profile and Schema <= 2.1.5 is vulnerable to Page creation and settings update leading to stored XSS vulnerability

The Five Star Business Profile and Schema WordPress plugin before 2.1.7 does not have any authorisation and CSRF in its bpfwp_welcome_add_contact_page and bpfwp_welcome_set_contact_information AJAX action, allowing any authenticated users, such as subscribers, to call them. Furthermore, due to the lack of sanitisation, it also lead to Stored Cross-Site Scripting issues
