Project: Mini site [1] Date: 2025-December-03 Security risk: *Moderately critical* 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] 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 [3]. 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.
