CVE-2025-70844
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 · uneditedyaffa 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 confidenceStored 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.

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 yaffa installationLocate the yaffa application directory or check running services for 'yaffa' or 'Kantorge Yaffa'Affected if yaffa is not installed or not running
-
Identify installed versionCheck the application's version information, typically found in the application metadata, about page, or version file within the yaffa installationAffected if version is not 2.0.0
-
Verify Add Account Group feature existsNavigate to the account group management interface in the yaffa web application and locate the Add Account Group functionAffected if the Add Account Group function does not exist in the interface
-
Inspect stored account group names for malicious payloadsAccess 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 tagsAffected if any account group name contains executable JavaScript or HTML markup
-
Test XSS execution in browserOpen 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 scriptAffected 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

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