A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Update to version 1.1.14, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Booking Ultra Pro Appointments Booking Calendar Plugin 1.1.14 closes this, and updating the plugin is the step that ends it.
