## Summary

The Booking for Appointments and Events Calendar (Amelia) plugin for WordPress is affected by this flaw, which lets someone without a login access sensitive data through a URL parameter. Exposed information can include staff names, email addresses, phone numbers, gender, time zones, and internal notes attached to published events.

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

## Affected

- melograno Booking for Appointments and Events Calendar – Amelia: through 2.4.12

## Description

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.
