Description
A vulnerability in SpiceJet’s booking API allows unauthenticated users to query passenger name records (PNRs) without any access controls. Because PNR identifiers follow a predictable pattern, an attacker could systematically enumerate valid records and obtain associated passenger names. This flaw stems from missing authorization checks on an endpoint intended for authenticated profile access.
