What the vulnerability does
01Description
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.6.0. This is due to missing or incorrect nonce validation on the change_status function. This makes it possible for unauthenticated attackers to change the status of arbitrary invoices — including marking unpaid invoices as paid — without administrator consent via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
