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
yaffa v2.0.0 is vulnerable to Cross Site Scripting (XSS). An attacker can inject malicious JavaScript into the "Add Account Group" function on the account-group page, allowing execution of arbitrary script in the context of users who view the affected page.

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

Stored XSS vulnerability in yaffa v2.0.0 where the Add Account Group function fails to sanitize user input, allowing injection of malicious JavaScript that executes in the browsers of users viewing the account-group page.

MitigationImplement strict input validation and output encoding/escaping on the Add Account Group function to neutralize malicious script payloads before storage and before rendering.

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 yaffa installation
    Locate the yaffa application directory or check running services for 'yaffa' or 'Kantorge Yaffa'
    Affected if yaffa is not installed or not running
  2. Identify installed version
    Check the application's version information, typically found in the application metadata, about page, or version file within the yaffa installation
    Affected if version is not 2.0.0
  3. Verify Add Account Group feature exists
    Navigate to the account group management interface in the yaffa web application and locate the Add Account Group function
    Affected if the Add Account Group function does not exist in the interface
  4. Inspect stored account group names for malicious payloads
    Access the account group data storage (database or configuration file) and retrieve all account group names; examine each name for unusual characters or patterns that resemble XSS payloads such as <script>, javascript:, onload, onerror, or HTML tags
    Affected if any account group name contains executable JavaScript or HTML markup
  5. Test XSS execution in browser
    Open the account-group page in a browser, view the list of account groups, and use browser developer tools to inspect whether the group name renders as raw HTML or executes script
    Affected if the account group name renders as HTML or executes JavaScript when viewed

User is affected if yaffa version 2.0.0 is installed AND the Add Account Group feature has been used to create an account group containing malicious script payloads that execute when the account-group page is viewed
