The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4.12 via the 'page' parameter. This makes it possible for unauthenticated attackers to extract staff personally identifiable information — including full name, email address, phone number, gender, and timezone — as well as administrator-authored internal notes for every published event, all serialized into the JSON response because the raw providers array is never stripped before output.
