CVE-2026-15250: Unknown Appointment Booking Plugin

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

The Appointment Booking Plugin WordPress plugin before 5.6.8 does not restrict which booking fields an unauthenticated visitor can set through its public booking funnel, allowing an unauthenticated user to assign a privileged booking field such as the approval status and thereby bypass the site's booking approval workflow.
