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 Ultra WordPress Admin plugin is installed
    Log into WordPress admin dashboard and navigate to Plugins > Installed Plugins, or inspect the wp-content/plugins/ directory for a folder containing 'ultra' and 'wordpress' in the name
    Affected if The plugin appears in the list of installed plugins
  2. Check installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate Ultra WordPress Admin to view the version number, or open the main plugin PHP file and look for the version header in the plugin comment block
    Affected if Version displayed is 11.7 or lower, or version cannot be determined (treat as potentially vulnerable)
  3. Verify plugin is active
    In WordPress admin under Plugins > Installed Plugins, confirm the Ultra WordPress Admin plugin shows as 'Active'
    Affected if Plugin is currently active on the WordPress site
  4. Identify reflected input parameters
    Access the plugin admin pages and observe URL parameters (such as ?page=, ?tab=, or custom parameters) that reflect user-supplied values back into the HTML output without sanitization
    Affected if Any URL parameter values are reflected verbatim in admin page content without encoding or escaping

If Ultra WordPress Admin plugin is installed, active, and version 11.7 or lower, and admin pages reflect URL parameters without sanitization, the environment is affected by this reflected XSS vulnerability.
