CyberRota Analysis
AI-GeneratedThe Easy Appointments WordPress plugin versions up to 3.12.26 is vulnerable due to inadequate verification of user ownership for appointment updates, allowing authenticated users to manipulate customer metadata of other users' appointments. This flaw can lead to unauthorized access to sensitive information and misdirected notifications, potentially compromising user privacy and trust. WordPress site administrators and users of the Easy Appointments plugin should prioritize applying the latest updates to mitigate this risk.
Original NVD Description
The Easy Appointments WordPress plugin before 3.12.28 does not verify that the appointment targeted by its customer-data update action belongs to the current user; the action only checks a shared nonce that any authenticated user can obtain from their own appointment's edit form. A subscriber-level user with an appointment of their own can therefore reuse that nonce to overwrite the customer metadata (email, name, phone, description) of another user's appointment. Because the Easy Appointments WordPress plugin before 3.12.28 then treats that metadata as the appointment's contact data, a subsequent administrator status change with customer notifications enabled delivers the victim's appointment notification to the attacker-controlled email address.
