CVE-2026-8684Network attack vector

Unauthenticated booking-note modification via unchecked AJAX action

Published May 22, 2026 · Updated May 22, 2026

Missing authorization in MotoPress Hotel Booking 6.0.1 and earlier allows remote attackers to overwrite or delete any booking's internal notes. The mphb_update_booking_notes AJAX action accepts an arbitrary booking ID and updates _mphb_booking_internal_notes without checking booking access. Every public page exposes the action nonce through MPHB._data.nonces, so exploitation requires neither an account nor prior interaction.
