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.
