Administrator-session script execution via unescaped friendlyTime
Published Oct 2, 2026 · Updated Oct 2, 2026
Stored cross-site scripting in Crocoblock JetAppointment 2.5.2.1 and earlier allows remote attackers to run script in an administrator's browser. The unauthenticated jet_engine_form_booking_submit endpoint stores unsanitized friendlyTime input in wp_jet_appointments_meta, and the appointment-details popup renders it without escaping. Execution requires an administrator to open the affected appointment popup; the injected script runs in that administrator's WordPress session.
