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 the download URL of another user to obtain the purchased ticket.

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 · moderate confidence

IDOR vulnerability in Janto Ticketing Software v4.3r10 allows a remote user to access another user's ticket download URLs by manipulating object references (ticket IDs) in requests, enabling unauthorized access to purchased tickets belonging to other users.

MitigationImplement proper authorization checks to verify ticket ownership before returning download URLs. Ensure the authenticated user has rights to access the specific ticket identifier being requested.

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. Verify Janto Ticketing Software version
    Locate the installed version of Janto Ticketing Software in the application (typically visible in the footer, about page, or admin panel) and confirm it is v4.3r10
    Affected if The installed version is v4.3r10 or falls within the same version branch where this IDOR was identified
  2. Confirm ticket download feature is accessible
    Log in as a standard user and navigate to your purchased tickets section to confirm the download URL functionality exists and is accessible
    Affected if The ticket download feature is present and returns URLs containing ticket ID parameters
  3. Test IDOR on ticket download endpoint
    Obtain a ticket download URL for your own purchased ticket (note the ticket ID parameter), then log in as a different user and attempt to access that same URL with the original user's ticket ID to see if the download is returned without authorization checks
    Affected if The system returns the ticket download for a ticket ID that does not belong to the currently authenticated user, indicating missing ownership validation
  4. Verify object reference enumeration is possible
    Attempt to increment or decrement the ticket ID parameter in the download URL to access tickets belonging to other users, observing whether the system returns unauthorized downloads
    Affected if Modifying the ticket ID to values belonging to other users successfully returns their ticket download URLs without proper authorization

The environment is affected if Janto Ticketing Software v4.3r10 is running and the ticket download endpoint returns tickets belonging to other users when their ticket IDs are requested by an authenticated user who does not own those tickets.
