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 · uneditedCross Site Scripting (XSS) vulnerability in skycaiji 2.8 allows attackers to run arbitrary code via /admin/tool/preview.
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 confidenceCross-site scripting (XSS) vulnerability in skycaiji version 2.8 at the /admin/tool/preview endpoint allows attackers to inject and execute arbitrary JavaScript code via unsanitized user input.

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 installed skycaiji versionLocate the version file or admin panel about page. Common locations include a version.php file, composer.json, or the admin dashboard's system information section.Affected if The installed version is exactly 2.8
-
Verify the /admin/tool/preview endpoint existsCheck if the web server responds to requests at /admin/tool/preview. This may require admin authentication depending on access controls.Affected if The endpoint is accessible and returns a preview function page
-
Confirm admin access is availableDetermine if you have or can obtain admin-level credentials to access the /admin/tool/preview functionality.Affected if You have administrative access to the skycaiji application
-
Test for reflected input in preview functionalitySubmit a test payload containing harmless HTML/script tags (such as <script>alert(1)</script> or <img src=x onerror=alert(1)>) to input fields on the /admin/tool/preview page and observe if the payload is rendered unescaped in the response.Affected if The submitted payload is reflected in the response without HTML encoding or is executed by the browser
You are affected if skycaiji version 2.8 is installed and the /admin/tool/preview endpoint reflects user-supplied input without proper sanitization, allowing script execution.

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 proper input validation and output encoding/escaping for all user-supplied data rendered in the preview functionality. Use context-appropriate escaping and consider Content Security Policy headers.
