CVE-2025-0614
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 · uneditedInput validation vulnerability in Qualifio's Wheel of Fortune. This vulnerability could allow an attacker to modify a single email to contain upper and lower case characters in order to access the application and win prizes as many times as wanted.
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 confidenceInput validation vulnerability in Qualifio's Wheel of Fortune allows attackers to bypass email-based prize limits by using mixed-case variations of the same email address. The application incorrectly treats email addresses as case-sensitive for uniqueness checks, enabling multiple prize redemptions through case-manipulated registrations (e.g., [email protected] vs [email protected]).

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.
-
Confirm Wheel of Fortune module is activeLocate the Wheel of Fortune configuration in the Qualifio admin panel or check the application module list to verify this feature is enabled for any campaign or promotion.Affected if The Wheel of Fortune feature is currently live and accepting user registrations.
-
Identify the email uniqueness mechanismExamine the application source code, database schema, or API endpoints that handle email registration for the Wheel of Fortune. Look for how email addresses are stored and compared (e.g., check if there is a UNIQUE constraint and whether it is case-sensitive).Affected if The email field uses a case-sensitive comparison or database constraint for uniqueness.
-
Test registration with case-variant emailsIn a test environment, attempt to register two accounts using the same email address with different capitalization (e.g., [email protected] and [email protected]) through the Wheel of Fortune promotion.Affected if Both registrations succeed and are treated as separate unique users.
-
Review prize redemption records for case variantsQuery the prize redemption or user registration database table for the Wheel of Fortune campaign. Search for entries where email addresses differ only by case (e.g., compare strings case-insensitively to find duplicates like [email protected] and [email protected]).Affected if Multiple prize claims exist from email addresses that are identical when normalized to lowercase.
-
Check prize limit enforcement logicInspect the application logic that enforces per-email prize limits. Determine whether the limit check performs case-insensitive comparison before blocking subsequent redemptions.Affected if The prize limit code performs case-sensitive email matching.
A user is affected if the application permits multiple prize redemptions from email addresses that differ only in capitalization, due to case-sensitive uniqueness checks.

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 dataNormalize all email inputs to lowercase before storage and comparison; implement case-insensitive uniqueness checks to prevent duplicate prize claims from case-variant email addresses.
