Rox Appointment Booking lets unauthenticated callers rewrite holidays
Rox Appointment Booking before 1.2.0 saves its holiday schedule without a capability or authorization check. An unauthenticated attacker can overwrite unavailable dates, block legitimate bookings, or reopen dates the owner intended to close. The authoritative export does not identify the endpoint, action, date parameter, or storage key.

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. The authoritative affected range ends before 1.2.0. The application-level fix must require an appropriate booking-management capability and nonce, validate the submitted dates, and limit updates to the authorized schedule.
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.
