WordPress Plugin Salon Booking System < 9.6.3 - Unauthenticated Stored Cross-Site Scripting (XSS)

The Salon booking system WordPress plugin before 9.6.3 does not properly sanitize and escape the 'Mobile Phone' field when booking an appointment, allowing customers to conduct Stored Cross-Site Scripting attacks. The payload gets triggered when an admin visits the 'Customers' page and the malicious script is executed in the admin context.
