What is CVE-2026-87891?
The Rox Appointment Booking plugin for WordPress is susceptible to an authorization bypass, which allows unauthorized users to modify the holiday schedule settings. Specifically, the plugin does not enforce capability or authorization checks when saving its holiday schedule. This flaw can enable attackers to change the dates that the booking system recognizes as unavailable, potentially disrupting legitimate bookings and overriding dates intended by the site owner to remain closed.
Affected Version(s)
Rox Appointment Booking 0 < 1.2.0
