Summary
The MotoPress Appointment Booking Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.4.8. The public /motopress/appointment/v1/customers/create REST endpoint is registered with permission_callback set to __return_true, and the handler's name parameter is neither sanitized before being written to the wp_mpa_customers table nor escaped when displayed in the admin bookings list for users without the mpa_edit_customer capability, such as the plugin-defined Appointment Employee role. Unauthenticated attackers can therefore inject scripts that execute whenever a user opens an affected page.

Description from the CNA
The MotoPress Appointment Booking Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.4.8 via the public '/motopress/appointment/v1/customers/create' REST endpoint. The route is registered with permission_callback => '__return_true' and the handler's 'name' parameter is not sanitized before being written to the custom wp_mpa_customers table via $wpdb->insert, nor is it escaped on output in the admin bookings list when the viewing user lacks the 'mpa_edit_customer' capability (such as the plugin-defined Appointment Employee role). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
