Put simply

Think of it like a restaurant where a cheeky chef serves a customer an unexpected dish—if the waiter doesn't check the order, it could lead to a surprise that nobody asked for!

It's a serious risk that could damage your reputation and user trust! Update your XStore theme to version 9.6.1 or later to squash this vulnerability.
