CVE-2026-45086 Details
Description
Decidim is a participatory democracy framework. From 0.31.1 before 0.31.5 and in 0.32.0.rc1 before 0.32.0.rc2, a participant can directly load /admin/demographics/questions/edit_questions and reach the demographics questionnaire editor without the required administrator authorization. The demographics questionnaire editor should require admin access, but the route under /admin/demographics/questions renders the editor interface without checking whether the caller is an admin. A normal participant can load the page and see the live update form action, which proves the protected interface is reachable. This issue is fixed in versions 0.31.5 and 0.32.0.rc2.
A vulnerability exists in the Decidim framework's demographics module, specifically in versions 0.31.1 prior to 0.31.5 and 0.32.0.rc1 prior to 0.32.0.rc2. The issue allows participants to access the demographics questionnaire editor without the necessary administrative privileges. The editor interface is rendered without proper authorization checks, enabling regular users to view and potentially modify content that should be restricted to administrators.
Users can update to Decidim versions 0.31.5 or 0.32.0 to address this vulnerability.
