The Service Finder Bookings plugin for WordPress, used by the Service Finder - Directory and Job Board WordPress Theme, is vulnerable to privilege escalation in all versions up to, and including, 5.1. This is due to a lack of restriction on user role in the 'nsl_registration_store_extra_input' function. This makes it possible for unauthenticated attackers to register an account on the site with an arbitrary role, including Administrator, when registering via a social login. The Nextend Social Login plugin must be installed and configured to exploit the vulnerability.
