CivicTheme Design System - Moderately critical - Cross-site Scripting - SA-CONTRIB-2025-113

Project: CivicTheme Design SystemDate: 2025-October-22Security risk: Moderately critical 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:AllVulnerability: Cross-site ScriptingAffected versions: <1.12.0CVE IDs: CVE-2025-12083Description: 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.
