Rox Appointment Booking trusts attacker-supplied prices and payment methods

Rox Appointment Booking before 1.2.0 creates bookings without recalculating the order total or validating the payment method against server-side configuration. An unauthenticated attacker can submit an arbitrary price, create a confirmed booking, and bypass the site's permitted payment methods. The authoritative export does not name the booking endpoint or price and payment fields.

Weakness
CWE-284 — Improper Access Control

This CVE was published Sep 12, 2026 and is one of 3 known issues for this plugin.

Update, patch or deactivate.

Update Rox Appointment Booking to 1.2.0 or later and audit suspicious booking totals and payment states. The application-level fix must calculate price, currency, discounts, and allowed payment methods entirely from trusted server-side records before confirming a booking.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Rox Appointment Booking WordPress plugin before 1.2.0 does not verify the order total or the selected payment method against its own server-side pricing when creating a booking, allowing unauthenticated attackers to create confirmed bookings at an arbitrary price and to bypass the site's configured payment-method restrictions.
