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 · uneditedQlikView 12.60.2 was discovered to contain a stored cross-site scripting (XSS) vulnerability in the QvsViewClient functionality.
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 cross-site scripting (XSS) vulnerability in QlikView 12.60.2's QvsViewClient functionality allows authenticated or unauthenticated attackers to inject malicious JavaScript that executes in the browsers of users who view the compromised content.

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.
-
Identify QlikView versionOpen QlikView Desktop or check the QlikView Server/QVS management console for the installed version number. The version is typically displayed in the About section or can be retrieved via QMS (QlikView Management Service) API.Affected if The installed version is 12.60 or lower, indicating the instance falls within the affected range (<=12.60).
-
Verify QvsViewClient accessibilityCheck if the QvsViewClient web interface is exposed and accessible. This is typically found at /QvAjaxZfc/QvsViewClient.aspx or similar paths on the QlikView Web Server. Attempt to access this endpoint from a browser.Affected if The QvsViewClient endpoint responds and is accessible, meaning the vulnerable component is exposed.
-
Inspect QlikView documents for unexpected contentReview QlikView documents (.qvw files) or list files accessible through the QvsViewClient interface for suspicious script tags, JavaScript event handlers, or encoded content that may indicate stored XSS payloads.Affected if Unexpected script tags or JavaScript code are found embedded in document content, sheet objects, or text objects that render through QvsViewClient.
A user is affected if their QlikView installation is version 12.60 or lower AND the QvsViewClient web interface is accessible, as this combination allows the stored XSS vulnerability to be exploited.

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 dataApply vendor patch or upgrade to a fixed version. Implement output encoding and input validation for all user-supplied data rendered by QvsViewClient.
