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
Authorization Bypass Through User-Controlled Key vulnerability in Universal Software Inc. FlexCity/Kiosk allows Exploitation of Trusted Identifiers. This issue affects FlexCity/Kiosk: from 1.0 before 1.0.36.

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 FlexCity/Kiosk application contains an IDOR (Insecure Direct Object Reference) vulnerability where user-controlled keys are not properly validated during authorization checks, allowing attackers to manipulate trusted identifiers to access unauthorized resources or functionality.

MitigationUpgrade to FlexCity/KiosK version 1.0.36 or later; implement proper authorization validation that does not rely on user-supplied identifiers for access decisions.

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 FlexCity/Kiosk installation version
    Locate the version file, about page, or admin interface that displays the current FlexCity/Kiosk application version. Check application metadata or deployment documentation if direct access is unavailable.
    Affected if The installed version is Uni Yaz Flexcity version 1.0 or higher but lower than 1.0.36
  2. Verify if user-supplied identifiers control access to resources
    Review application source code, configuration, or API endpoints to determine whether authorization checks rely on identifiers (such as IDs, keys, or references) that originate from user input rather than from trusted internal sources.
    Affected if User-supplied identifiers are directly used in authorization decisions without validation against the authenticated user's permissions
  3. Inspect authorization logic for missing validation
    Examine the authorization module or middleware that handles resource access control. Look for patterns where object references (keys, IDs) passed in requests are trusted without verifying the requesting user has rights to that specific object.
    Affected if The authorization logic does not validate that the authenticated user owns or has permission to access the resource identified by the user-supplied key
  4. Check application logs for anomalous access patterns
    Review access logs, audit trails, or security event logs for requests that manipulate identifier parameters (such as sequential IDs, UUIDs, or record keys) across different user contexts, which may indicate exploitation attempts.
    Affected if Logs show access attempts using manipulated identifiers that deviate from expected user resource boundaries

You are affected if the FlexCity/Kiosk version is 1.0 or higher but below 1.0.36 AND the application uses user-supplied identifiers in its authorization logic without proper validation.

Upgrade available Upgrade to 1.0.36 or later
Fixed in 1.0.36
Interim mitigation

Upgrade to FlexCity/KiosK version 1.0.36 or later; implement proper authorization validation that does not rely on user-supplied identifiers for access decisions.

Recommended fix High confidence

FlexCity/Kiosk version 1.0.36

  1. Upgrade FlexCity/Kiosk from the current version (>=1.0 and <1.0.36) to version 1.0.36 or later
  2. After upgrading, verify the installed version is 1.0.36 or higher to confirm the vulnerability is remediated
