{"id":"GHSA-q79h-67vx-m9xg","summary":"Decidim: CSV census record endpoints improper authorization","details":"## Description\n\nA participant manager can access and modify the CSV census record admin forms.\n\n## Technical description\n\nThe CSV census admin record-management surface under `/admin/csv_census/census_logs` does not enforce admin-only authorization before rendering or mutating `Decidim::Verifications::CsvDatum`.\n\nA participant manager (which can only manage participants) can therefore open the admin forms, create or update census rows, and delete rows directly.\n\nReproduction steps:\n1. Sign in a participant admin and open `http://localhost:3000/admin/csv_census/census_logs/new_record` in the browser. Confirm the create form loads even though the session is not a full admin.\n\n\u003cimg width=\"1541\" height=\"274\" alt=\"decidim-census-01\" src=\"https://github.com/user-attachments/assets/859ee101-746f-4acb-8051-27036689f1b3\" /\u003e\n\n\u003cimg width=\"1538\" height=\"363\" alt=\"decidim-census-02\" src=\"https://github.com/user-attachments/assets/85bbb004-a999-46dc-856c-fd32b50ced2c\" /\u003e\n\nNote that normal participant accounts were not able to access the CSV census records which is good.\n\n### Impact\n \nAny participant admin can create, alter, or remove CSV census rows, which can corrupt verification data relied on by authorization workflows.\n\n### Patches\n\nSee https://github.com/decidim/decidim/pull/16674 and https://github.com/decidim/decidim/pull/16703 \n\n### Workarounds\n\nDisable Organization Census verification method\n\n### Reference\n\nOWASP A01:2021 Broken Access Control\n\n### Credits\n\nThis issue was discovered in a security audit organized by the [Decidim Association](https://decidim.org) and made by [Radically Open Security](https://www.radicallyopensecurity.com/) against Decidim financed by [NGI](https://ngi.eu/).","aliases":["CVE-2026-45415"],"modified":"2026-07-13T17:41:46.799394Z","published":"2026-07-13T17:17:33Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-285"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-07-13T17:17:33Z"},"references":[{"type":"WEB","url":"https://github.com/decidim/decidim/security/advisories/GHSA-q79h-67vx-m9xg"},{"type":"WEB","url":"https://github.com/decidim/decidim/pull/16674"},{"type":"WEB","url":"https://github.com/decidim/decidim/pull/16703"},{"type":"PACKAGE","url":"https://github.com/decidim/decidim"}],"affected":[{"package":{"name":"decidim-verifications","ecosystem":"RubyGems","purl":"pkg:gem/decidim-verifications"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.30.9"}]}],"versions":["0.10.0","0.10.1","0.11.0.pre1","0.11.1","0.11.2","0.12.0","0.12.0.pre","0.12.1","0.12.2","0.13.0","0.13.0.pre1","0.13.1","0.14.1","0.14.2","0.14.3","0.14.4","0.15.0","0.15.1","0.15.2","0.16.0","0.16.1","0.17.0","0.17.1","0.17.2","0.18.0","0.18.1","0.19.0","0.19.1","0.20.0","0.20.1","0.21.0","0.22.0","0.23.0","0.23.1","0.23.1.rc1","0.23.2","0.23.3","0.23.4","0.23.5","0.23.6","0.24.0","0.24.0.rc1","0.24.0.rc2","0.24.1","0.24.2","0.24.3","0.25.0","0.25.0.rc1","0.25.0.rc2","0.25.0.rc3","0.25.0.rc4","0.25.1","0.25.2","0.26.0","0.26.0.rc1","0.26.0.rc2","0.26.1","0.26.10","0.26.2","0.26.3","0.26.4","0.26.5","0.26.7","0.26.8","0.26.9","0.27.0","0.27.0.rc1","0.27.0.rc2","0.27.1","0.27.10","0.27.2","0.27.3","0.27.4","0.27.5","0.27.6","0.27.7","0.27.8","0.27.9","0.28.0","0.28.0.rc4","0.28.0.rc5","0.28.1","0.28.2","0.28.3","0.28.4","0.28.5","0.28.6","0.29.0","0.29.0.rc1","0.29.0.rc2","0.29.0.rc3","0.29.0.rc4","0.29.1","0.29.2","0.29.3","0.29.4","0.29.5","0.29.6","0.29.7","0.30.0","0.30.0.rc1","0.30.0.rc2","0.30.0.rc3","0.30.1","0.30.2","0.30.3","0.30.4","0.30.5","0.30.6","0.30.7","0.30.8","0.8.0","0.8.1","0.8.2","0.8.3","0.8.4","0.9.0","0.9.1","0.9.2","0.9.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-q79h-67vx-m9xg/GHSA-q79h-67vx-m9xg.json"}},{"package":{"name":"decidim-verifications","ecosystem":"RubyGems","purl":"pkg:gem/decidim-verifications"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.31.0.rc1"},{"fixed":"0.31.5"}]}],"versions":["0.31.0","0.31.0.rc1","0.31.0.rc2","0.31.1","0.31.2","0.31.3","0.31.4"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-q79h-67vx-m9xg/GHSA-q79h-67vx-m9xg.json"}},{"package":{"name":"decidim-verifications","ecosystem":"RubyGems","purl":"pkg:gem/decidim-verifications"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.32.0.rc1"},{"fixed":"0.32.0"}]}],"versions":["0.32.0.rc1","0.32.0.rc2","0.32.0.rc3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-q79h-67vx-m9xg/GHSA-q79h-67vx-m9xg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:L"}]}
