The Tripzzy WordPress plugin before 1.5.1 does not perform any capability or ownership checks on its administrative booking-management actions, which are additionally exposed to unauthenticated users and gated only by a token the Tripzzy WordPress plugin before 1.5.1 issues to any anonymous visitor on request, allowing unauthenticated attackers to alter the contents, stored totals and notes of arbitrary bookings.
