Security risk: 
Moderately critical 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All
Vulnerability: 
Cross-Site Scripting
Affected versions: 
<3.0.2
CVE IDs: 
CVE-2025-13979
Description: 

This module allows uploading a zip file and extracting its content in the public file directory to serve this content from a Drupal website.

These zip files may contain arbitrary HTML or SVG content that could allow cross-site scripting vulnerabilities. While this is an expected feature, the module does not sufficiently restrict this functionality to trusted users with a "restricted access" permission. Users without a restricted permission should not be able to inject arbitrary JavaScript.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission create [bundle] content permission.

Solution: 

Two steps are required. Install the latest version and adjust configuration:

  1. If you use Mini site 2.x or 3.x versions, upgrade to the Mini site 3.0.2.

  2. A new manage minisites permission has been added. This new permission will need to be assigned to a trusted role for the user to be able to upload the zip file.
