Boarding pass information is travel data used to identify a passenger and link them to a flight record. It may include a name, confirmation or booking reference, flight number, seat assignment, barcode or QR data, and other trip-specific details. In some systems, this information acts as a lightweight identifier that helps staff and software retrieve a passenger’s itinerary.
In cyber security, boarding pass information matters because it can become a convenient lookup key for protected records. If an API or portal trusts that data too much, an attacker may be able to enumerate bookings, view personal details, or reach passport and payment data without proper authorization. Defenders should treat boarding-pass-linked workflows as sensitive, verify access on every request, and return only the minimum data needed. That reduces the risk of object-level authorization flaws and limits the damage if a reference number is exposed.
