CVE-2026-6376Network attack vector

Passenger booking disclosure via unauthenticated retrieval

Published Apr 23, 2026 · Updated Apr 23, 2026

Missing authentication in SpiceJet Online Booking System allows remote attackers to read booking details using a PNR and last name. The public booking retrieval page accepts those two identifiers and returns full passenger, travel, and booking metadata without authentication or secondary verification. Exploitation requires a valid or guessed PNR and matching last name; successful requests disclose records but do not alter bookings or interrupt service.
