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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-45086)\n\nAffected packages:\n\n- `decidim-demographics >= 0.31.0, < 0.31.5`\n- `decidim-demographics >= 0.32.0.rc1, < 0.32.0`\n\nPatched in:\n\n- `decidim-demographics 0.31.5`\n- `decidim-demographics 0.32.0`\n\nSource: https://github.com/advisories/GHSA-vq6j-hj8w-7v39","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
