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

Cross-Site Scripting (XSS) vulnerability in AcyMailing Enterprise component for Joomla allows attackers to inject malicious scripts through unsanitized user input that gets rendered in web pages. The vulnerability affects versions 6.7.0 through 8.6.3 and stems from improper neutralization of input during web page generation.

MitigationUpdate AcyMailing Enterprise to a version beyond 8.6.3 which contains the patched build, or apply vendor-supplied sanitization/encoding to all user-supplied input fields in the component.

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 AcyMailing installation
    Log into the Joomla Administrator panel, navigate to Extensions > Manage > Manage, and search for 'AcyMailing' in the extensions list to verify the component is installed.
    Affected if The AcyMailing component appears in the extensions list
  2. Identify installed AcyMailing version
    In the Joomla Administrator panel, go to Components > AcyMailing. The version number is typically displayed on the main component page or in the system information area. Alternatively, check the version in the #__extensions database table for the AcyMailing plugin/component entry.
    Affected if The displayed version falls within 6.7.0 through 8.6.3
  3. Determine exposure to user input fields
    Navigate to the front-end of the Joomla site and identify any AcyMailing subscription forms, newsletter signup forms, or user profile fields. Also check the AcyMailing admin panel for any user management interfaces where user-submitted data is displayed.
    Affected if AcyMailing subscription forms or user management interfaces are accessible on the site
  4. Verify unsanitized output rendering
    Inspect the HTML source code of AcyMailing front-end forms (subscription forms, archive pages) by viewing the page source. Look for form fields that accept user input and check if the output is rendered without proper encoding. Use browser developer tools to examine form submission parameters and their reflected values in the response.
    Affected if User-supplied input fields in AcyMailing are rendered back to the page without HTML encoding or sanitization

You are affected if AcyMailing Enterprise is installed with a version between 6.7.0 and 8.6.3 and the component's user input fields are accessible on your Joomla site.
