Project: CivicTheme Design System [1]
Date: 2025-October-22
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: <1.12.0
CVE IDs: CVE-2025-12083
Description: 
CivicTheme is a design system and theme framework used to build content-rich
Drupal websites. It includes editorial workflows, structured content types,
and flexible theming components.

CivicTheme does not sufficiently filter field data before rendering them in
Twig templates. This combined with multiple instances of the Twig raw filter
throughout CivicTheme components, allows for the injection of malicious
scripts in browser contexts.

Additionally, CivicTheme fails to filter markup from SVGs embedded within the
web page  allowing potentially malicious scripts to be injected.

This vulnerability is mitigated by an attacker needing permission to create
or edit content within a CivicTheme site.

CivicTheme with its default permissions restricts the creation of content to
content author and content approver roles.

Solution: 
Install the latest version:

  * If you use the CivicTheme theme, upgrade to CivicTheme 1.12 [3].
