Booking.com Customer Details Exposed — April 2026

If you are a customer of Booking.com, here’s what’s now in circulation.

A breach of Booking.com customer-detail records was disclosed in April 2026, with travel-history data fueling location-based doxxing risk.

A breach of Booking.com customer records was disclosed in April 2026. The exposed dataset includes names, email addresses, booking history, and travel dates and destinations. Travel-history data is one of the highest-risk categories for location-based doxxing — an attacker with your name and your scheduled hotel arrival can intercept you in person.
