CVE-2026-16582: Melograno Booking For Appointments And Events Calendar – Amelia

Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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
