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 UnboundStudio Accordion FAQ allows Reflected XSS. This issue affects Accordion FAQ: from n/a through 2.2.1.

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 UnboundStudio Accordion FAQ plugin (versions up to 2.2.1) allows attackers to inject malicious JavaScript through unsanitized user input that gets reflected in the generated web page.

MitigationUpdate to a patched version when available, or implement proper input validation and output encoding on all user-supplied parameters before rendering in HTML context.

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 Accordion FAQ plugin installation
    Inspect your website's plugin directory or CMS plugin list for 'Accordion FAQ' by UnboundStudio
    Affected if The plugin is present in the system
  2. Identify installed version number
    Check the plugin header file (usually in the main PHP file) or the plugin metadata displayed in your CMS admin panel for the version string
    Affected if Version cannot be determined or is earlier than the fixed release
  3. Locate user input reflection points
    Review the plugin's PHP files for parameters that accept user input (GET/POST requests) and are output without sanitization - look for functions like $_GET, $_POST, or $_REQUEST used in echo/print statements
    Affected if User-supplied parameters are found in the code and reflected in HTML output without visible escaping functions
  4. Test for reflected XSS in search or FAQ submission fields
    If accessible, submit a benign test payload like <script>alert('test')</script> in the plugin's search bar or FAQ submission form and observe if the script executes in the response
    Affected if The test payload appears unescaped in the rendered page source or executes in the browser
  5. Inspect HTTP response headers and output
    Capture the HTTP response when submitting input through the plugin and examine if Content-Type is set to text/html with the input reflected verbatim
    Affected if Input is reflected back in the HTML body without HTML entity encoding

You are affected if the UnboundStudio Accordion FAQ plugin is installed and user input is reflected in web pages without proper HTML escaping, regardless of the specific version until a patched release is confirmed.
