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
Wade Graphic Design FANTSY has a vulnerability of insufficient authorization check. An unauthenticated remote user can exploit this vulnerability by modifying URL parameters to gain administrator privileges to perform arbitrary system operation or disrupt service.

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

The vulnerability is an IDOR (Insecure Direct Object Reference) authorization bypass where an unauthenticated attacker can manipulate URL parameters to access administrative functions and elevate privileges to administrator level.

MitigationImplement proper server-side authorization checks on all sensitive operations and verify user permissions before allowing access to administrative functions or privilege escalation.

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. Confirm installed product is Wddgroup Fantsy
    Inspect the web application banner, footer, or source code for the product name 'Wddgroup Fantsy' or check the application's documentation/deployment files.
    Affected if The product name 'Fantsy' by Wddgroup is present in the application
  2. Identify the installed version
    Check the application version displayed in the UI, or examine configuration files, changelogs, or the application's metadata for version number 2.1.8.
    Affected if The installed version is exactly 2.1.8
  3. Inspect URL parameter handling for admin functions
    Examine HTTP requests and responses when accessing administrative pages or privilege-related endpoints. Look for predictable parameters like user_id, role, or admin flags in URLs.
    Affected if URL parameters can be manipulated to access admin functions without proper authorization checks
  4. Test for unauthorized privilege escalation
    Attempt to access higher-privilege functions or administrative panels by modifying URL parameters or form inputs that reference user roles or permissions.
    Affected if An unauthenticated or low-privilege user can elevate privileges to administrator level through parameter manipulation

A user is affected if they have Wddgroup Fantsy version 2.1.8 running and the application allows URL parameter manipulation to access admin functions or escalate privileges without proper authorization.
