Privilege Escalation in Flex Store Users WordPress Plugin <= 1.1.0
CVE-2025-13619 is a critical privilege escalation vulnerability in the Flex Store Users WordPress plugin, affecting all versions up to and including 1.1.0. The vulnerability arises from insufficient restrictions in the 'fsUserHandle::signup' and 'fsSellerRole::add_role_seller' functions, which fail to properly validate or restrict the user roles that can be assigned during registration. As a result, an unauthenticated attacker can specify the 'administrator' role via the 'fs_type' parameter (when the Flex Store Seller plugin is also active) and register as a site administrator, thereby gaining full administrative access to the WordPress site.
