At a glance
CVE-2026-9830 is a medium-severity Missing Authorization vulnerability in the BookingPress Appointment Booking Pro WordPress plugin, affecting versions <= 5.7.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.7.3; sites on affected versions should update now. Disclosed July 2026, reported by Kolja Zuelsdorf.
Vulnerability Overview
The BookingPress Appointment Booking Pro plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 5.7.2. This makes it possible for unauthenticated attackers to extract customer data and tamper with bookings.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in BookingPress Appointment Booking Pro <= 5.7.2 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For BookingPress Appointment Booking Pro the fix is 5.7.3: builds <= 5.7.2 are affected, anything from 5.7.3 onward is not.
Remediation
Update to version 5.7.3, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: BookingPress Appointment Booking Pro 5.7.3 closes this, and updating the plugin is the step that ends it.
