Unauthenticated free bookings via negative tips
Published Apr 9, 2026 · Updated Apr 9, 2026
Price manipulation in Bookly 27.0 and earlier allows remote attackers to reduce paid booking totals to zero via a negative tips value. UserBookingData::fillData blindly assigns the request's tips property, and CartInfo incorporates that signed value into the booking total without a nonnegative bound. The public booking workflow requires no account; the bounded consequence is a zero-price booking rather than data disclosure or service interruption.
