## Summary

Booking for Appointments and Events Calendar (WordPress plugin "Amelia") versions up to and including 9.9.1 let an attacker remotely, without logging in, read the personal details of event attendees, including names, emails, phone numbers, and payment information. The flaw is a missing authorization check on the attendee export function, so any event's attendee list can be requested by ID.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- melograno Booking for Appointments and Events Calendar – Amelia: from 9.0, through 9.9.1

## Description

The Amelia plugin for WordPress is vulnerable to unauthorized access of attendee data due to a missing authorization check on the GetEventAttendeesCommandHandler::handle() function in versions up to, and including, 9.9.1. The handler only enforces the broad `amelia_read_events` capability — which the plugin's own `wpamelia-customer` role possesses — and does not verify that the authenticated user is an organizer/provider of the event referenced by the client-supplied `id` query parameter. This makes it possible for authenticated attackers, with wpamelia-customer-level access and above, to export the full CSV of attendee personally identifiable information (first/last name, email, phone, date of birth, gender, private notes, payment amounts/methods, WooCommerce order IDs, custom-field values, and uploaded-file URLs) for any Amelia event on the site by directly invoking the `/report/event/attendees` endpoint with an arbitrary event ID.
