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
QuickCMS is vulnerable to Reflected XSS via sLangEdit parameter in admin's panel functionality. A malicious attacker can craft a specially crafted URL that, when opened, results in arbitrary JavaScript execution in the victim's browser. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.8 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

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

QuickCMS version 6.8 contains a reflected XSS vulnerability in the admin panel's sLangEdit parameter. The parameter accepts unsanitized user input which is reflected back in the HTTP response without proper encoding, allowing attackers to inject arbitrary JavaScript that executes in the victim's browser when they access a specially crafted URL.

MitigationImplement input validation and output encoding (HTML escaping) for the sLangEdit parameter in the admin panel, following OWASP XSS prevention guidelines. Consider implementing a Content Security Policy (CSP) as a defense-in-depth measure.

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 Quick.cms installation
    Look for Quick.cms files on your web server. Check common web root directories for folders named 'quick.cms', 'Quick', or files like 'index.php' with QuickCMS branding. Search for files containing 'Quick.cms' or 'quick' in page source/footers.
    Affected if QuickCMS is not present on the server, the system is not affected.
  2. Check installed Quick.cms version
    Locate the version identifier in the installation. Common locations include: a version.php or config file, the footer of admin panel pages, or an 'about' page in the admin interface. Look for a file that defines the application version.
    Affected if The installed version is 6.8, proceed to next checks.
  3. Verify admin panel accessibility
    Access the admin panel URL (typically /admin.php or /Quick/Admin/index.php). Check if the admin panel is reachable and requires authentication.
    Affected if Admin panel is not accessible or not configured, the vulnerability cannot be exploited.
  4. Identify sLangEdit parameter usage
    In the admin panel, navigate to language settings or localization features. Look for a parameter named 'sLangEdit' in URL query strings or form submissions. This parameter typically appears when editing language files.
    Affected if The sLangEdit parameter is not used or present in your installation, the vulnerability does not apply.
  5. Test for reflected XSS in sLangEdit
    In the admin panel with sLangEdit parameter present, inject a test payload like '<script>alert(1)</script>' into the sLangEdit value in the URL (example: ?sLangEdit=<script>alert(1)</script>). Examine the HTTP response to see if the payload is reflected without encoding.
    Affected if The payload reflects unencoded in the response, the system is vulnerable to CVE-2025-55175.

The system is affected only if Quick.cms version 6.8 is installed, the admin panel is accessible, and the sLangEdit parameter reflects unsanitized input in HTTP responses.
