Flex Store Users <= 1.1.0 - Unauthenticated Privilege Escalation
Vulnerability Description
The Flex Store Users plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.1.0. This is due to the 'fsUserHandle::signup' and the 'fsSellerRole::add_role_seller' functions not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site. Note: The vulnerability can be exploited with the 'fs_type' parameter if the Flex Store Seller plugin is also activated.
