CVE-2026-6376
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA weakness in SpiceJet’s public booking retrieval page permits full passenger booking details to be accessed using only a PNR and last name, with no authentication or verification mechanisms. This results in exposure of extensive personal, travel, and booking metadata to any unauthenticated user who can obtain or guess those basic inputs. The issue arises from improper access control on a sensitive data retrieval function.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSpiceJet's booking retrieval endpoint lacks proper access control, allowing unauthenticated users to retrieve complete passenger booking details (including personal information, travel itineraries, and booking metadata) by simply supplying a PNR and last name. This represents a classic Insecure Direct Object Reference (IDOR) vulnerability where the sensitive retrieval function performs no authorization verification against the requesting user.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the booking retrieval endpointSearch application source code and API documentation for endpoints that handle PNR (Passenger Name Record) and last name parameters for booking lookupsAffected if An endpoint accepting PNR and last name exists in the environment
-
Verify authentication is requiredAttempt to access the booking endpoint without providing any session token, API key, or login credentialsAffected if The endpoint returns booking data or accepts the request without requiring authentication
-
Confirm authorization validationSubmit a valid PNR and last name from one account, then attempt the same request from a different unauthenticated or different-user session to see if booking data is returnedAffected if The endpoint returns full booking details (passenger info, itinerary, metadata) without verifying the requester is authorized to access that specific booking
-
Check for additional verification factorsInspect whether the endpoint requires secondary verification such as OTP, CAPTCHA, or other factors beyond PNR and last nameAffected if The endpoint returns sensitive booking data using only PNR and last name without additional verification steps
Your environment is affected if the booking retrieval endpoint returns complete passenger booking details without requiring both authentication and authorization verification for the specific booking being requested.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement multi-factor verification (e.g., email/phone OTP, CAPTCHA) or require additional authentication factors before returning booking data. Also implement rate limiting to prevent automated enumeration of PNRs.
