CVE-2026-77689
Last modified
CVE-2026-77689 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. The Booking for Appointments and Events Calendar WordPress plugin before 9.8.1 does not verify that a payment was actually taken before recording a booking as paid, trusting the payment gateway named in a public, unauthenticated booking request even when the site has never configured that gateway. This lets an unauthenticated attacker obtain confirmed, fully paid appointments and events without any payment being collected.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
