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 Helix Ultimate extension is installed
    Log into the Joomla administrator backend and navigate to Extensions > Manage > Manage. Search for 'Helix Ultimate' in the extensions list to verify the extension is present on the system.
    Affected if The Helix Ultimate extension is found installed in Joomla.
  2. Identify installed Helix Ultimate version
    In the Joomla administrator, go to Extensions > Manage > Manage. Locate Helix Ultimate in the list and check the 'Version' column displayed for the extension.
    Affected if The installed version is 2.2.6 or lower, or if the version column shows a version less than 2.2.7.
  3. Check Helix Ultimate template configuration for injected scripts
    Navigate to Components > Helix Ultimate > Templates. Review any custom code, custom CSS, or JavaScript fields in the template settings for unfamiliar or suspicious script tags, especially those containing 'script' tags with external sources or event handlers like onload, onerror, or onmouseover.
    Affected if Suspicious script tags or JavaScript code that was not authored by an administrator is found in the template configuration.
  4. Inspect Helix Ultimate database tables for XSS payloads
    Access the Joomla database via phpMyAdmin or command line and examine tables that store Helix Ultimate data, such as those with 'helix' or 'ultimate' in the name. Look for stored records containing '<script>', 'javascript:', or HTML event attributes in fields that should contain only plain text.
    Affected if Database records contain XSS payloads such as script tags or event handlers that could execute in user browsers.

The environment is affected if Helix Ultimate version 2.2.6 or lower is installed, or if suspicious script injections are found in Helix Ultimate template configuration or related database tables.
