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
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in NooTheme CitiLights noo-citilights allows Reflected XSS.This issue affects CitiLights: from n/a through <= 3.7.1.

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

Reflected XSS vulnerability in NooTheme CitiLights theme allows attackers to inject malicious scripts through unsanitized user input that gets reflected in web pages. The vulnerability exists in the theme's web page generation logic.

MitigationImplement proper input validation and output encoding/escaping for all user-supplied data before rendering in HTML context. Update to the latest CitiLights version if available.

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 CitiLights theme is installed
    Locate the CitiLights theme directory in the CMS (typically under /wp-content/themes/ for WordPress or /themes/ for other CMS platforms). Check for a folder named 'citilights' or similar.
    Affected if The CitiLights theme folder exists in the system's theme directory.
  2. Identify the installed CitiLights version
    Open the theme's main style.css file or a version.php/version.json file within the CitiLights theme folder. Look for a 'Version:' comment or $version variable.
    Affected if The version cannot be determined or is lower than any available patched version.
  3. Locate user input reflection points in theme files
    Search theme PHP files for unsanitized use of superglobal variables ($_GET, $_POST, $_REQUEST, $_COOKIE) that are output to HTML. Look for patterns like echo $_GET['param']; or similar without htmlspecialchars(), esc_html(), or similar sanitization functions.
    Affected if User-supplied parameters from URL query strings or form submissions are directly echoed to HTML output without sanitization.
  4. Identify vulnerable page templates
    Examine theme template files (header.php, footer.php, search.php, archive.php, single.php, page.php) for $_REQUEST or $_GET usage in the page body. Check if these values are displayed without escaping.
    Affected if Template files contain code that reflects URL parameters or form inputs directly into the page content.
  5. Test for reflected XSS manually
    Using a browser or testing tool, visit pages on the site with a test XSS payload in URL parameters (e.g., ?search=<script>alert(1)</script>). Check if the payload appears unescaped in the page response.
    Affected if The test payload renders as executable JavaScript or appears literally in the page without being HTML-encoded.

The environment is affected if the CitiLights theme is installed and its code reflects URL parameters or form inputs directly into web pages without proper HTML encoding.
