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 · unedited
IDOR vulnerability in Janto Ticketing Software affecting version 4.3r10. This vulnerability could allow a remote user to obtain a user's event ticket by creating a specific request with the ticket reference ID, leading to the exposure of sensitive user data.

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 confidence

IDOR vulnerability in Janto Ticketing Software v4.3r10 allows authenticated or anonymous remote attackers to access event tickets belonging to other users by manipulating the ticket reference ID in requests. The application fails to validate that the requesting user has proper ownership or authorization to view the specific ticket, leading to unauthorized disclosure of sensitive user data including personal information associated with tickets.

MitigationImplement proper authorization checks to verify the requesting user owns or has permission to access the requested ticket before returning any ticket data. Additionally, consider implementing supplementary authentication mechanisms and logging/alerting for suspicious access patterns.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Janto Ticketing Software installation
    Check the application banner, headers, or system information to confirm the product is Janto Ticketing Software and note the exact version number
    Affected if The installed version is Janto Ticketing Software v4.3r10
  2. Locate ticket viewing functionality
    Identify endpoints or interfaces in the application that display individual ticket details, typically involving a ticket ID or reference number parameter in the request
    Affected if The application has a feature to view individual tickets using an ID parameter in the request
  3. Test authenticated IDOR access
    As a logged-in user, attempt to access ticket details by modifying the ticket reference ID parameter in the request to a value belonging to a different user
    Affected if The application returns ticket data belonging to another user without verifying that the requesting user owns or has permission to view that ticket
  4. Test anonymous IDOR access
    Without logging in, attempt to access ticket details by directly supplying a ticket reference ID in the request
    Affected if The application returns ticket data without requiring authentication or performing ownership validation
  5. Verify authorization logic exists
    Inspect the application code or configuration related to ticket retrieval to confirm whether ownership or permission checks are implemented before returning ticket data
    Affected if No ownership or authorization verification is performed before returning ticket data

A user is affected if they run Janto Ticketing Software v4.3r10 and the application allows accessing tickets belonging to other users by manipulating ticket reference IDs without proper ownership validation.
