The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Improper Authorization in all versions up to, and including, 2.1.2. This is due to a logical short-circuit flaw in authorization logic that causes token validation to be entirely skipped when a booking has a 'waiting' status. This makes it possible for unauthenticated attackers to approve any booking that is in 'waiting' status by sending a crafted request to the publicly-accessible admin-ajax endpoint.
CVE-2026-6449 is a medium severity with CVSS 5.3 Authorization Bypass issue affecting the Plugin Booking for Appointments and Events Calendar – Amelia. It affects Versions up to 2.1.2 and is fixed in 2.3.
CVE-2026-6449 is tracked for the Plugin Booking for Appointments and Events Calendar – Amelia as medium severity with CVSS 5.3. The affected range is Versions up to 2.1.2. Update Booking for Appointments and Events Calendar – Amelia to 2.3 or newer where that version is compatible with the site.
