CVE-2026-6375Network attack vector

Passenger-data disclosure via predictable PNR enumeration

Published Apr 23, 2026 · Updated Apr 23, 2026

Authorization bypass in SpiceJet Online Booking System allows remote attackers to read passenger names by enumerating predictable PNRs. The booking API accepts a user-controlled, predictable PNR and returns the corresponding record without verifying entitlement to it. No account or user interaction is required; successful enumeration discloses passenger names but does not alter bookings or interrupt service.
