CVE-2026-16582

Booking for Appointments and Events Calendar - Amelia <= 2.4.5 - Missing Authorization to Unauthenticated Payment Bypass

Published Sep 17, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 2.4.5. This is due to the plugin accepting a client-supplied package-redemption identifier as proof of payment without validating it. This makes it possible for unauthenticated attackers to create approved appointment bookings without completing payment
