 "title": "Timetics – Appointment Booking Calendar & Scheduling <= 1.0.66 - Missing Authorization to Existing User Account Modification via Guest Booking",
 "description": "The Timetics – Appointment Booking Calendar & Scheduling plugin for WordPress is vulnerable to unauthorized modification of data via the public booking endpoint (/timetics/v1/bookings) in all versions up to, and including, 1.0.66, due to a missing ownership or capability check in Customer::make() when the submitted email belongs to an existing user. This makes it possible for unauthenticated attackers to add the timetics-customer role to any existing account, including administrators, and to overwrite the stored first name, last name and phone number of existing Timetics customers by submitting a booking with that user's email address.",
