What the vulnerability does
The Appointment Booking Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.4.02 via the cpabc_appointments_filter_list. This makes it possible for authenticated attackers, with contributor-level access and above, to extract customer names, email addresses, phone numbers, appointment comments, and other booking personally identifiable information.

An attacker with a low-privilege account can read data belonging to other users or the system without additional interaction. This affects confidentiality but not data integrity or availability.
What an attacker can do
