{"id":"GHSA-86fh-w43w-338c","summary":"Decidim: Verification admins can access supplied IDs from other organizations","details":"## Description\n\nThe verification admin mutation flow allows accessing, verifying, and rejecting participants records from another tenant.\n\n## Technical description\n\nThe verification admin controllers loads pending_authorization_id with a raw `Authorization.find(...)` and then authorizes the record without checking whether it belongs to current_organization.\n\nReproduction steps:\n\n1. An org2 participant uploads their ID:\n\n\u003cimg width=\"2184\" height=\"1288\" alt=\"decidim-verification-01\" src=\"https://github.com/user-attachments/assets/c6713454-c787-4795-b852-3c2c672358d6\" /\u003e\n\n2. An admin from another organisation, in this case org1, is able to open the ID from org2 by opening request 35, e.g `http://localhost:3001/admin/id_documents/pending_authorizations/35/confirmations/new`\n\n\u003cimg width=\"1539\" height=\"1037\" alt=\"decidim-verification-02\" src=\"https://github.com/user-attachments/assets/6ed646de-a501-4964-8467-013ada55ce2d\" /\u003e\n\n3. The admin then approves this request by looking up the ID in the picture (not shown in this image, but a real ID would expose this)\n \n\u003cimg width=\"1542\" height=\"652\" alt=\"decidim-verification-03\" src=\"https://github.com/user-attachments/assets/c7ee5bea-3fa2-43d9-8330-8d834f34a9af\" /\u003e\n\n4. Now the request has been approved, which can be seen from the org2 participant authorizations page:\n\n\u003cimg width=\"2279\" height=\"720\" alt=\"decidim-verification-04\" src=\"https://github.com/user-attachments/assets/55ee1bab-d396-4e0f-803f-21dc31a2c125\" /\u003e\n\n### Impact\n\nA tenant admin can access, reject or approve another tenant's `id_documents` requests.\n\n### Patches\n\nSee https://github.com/decidim/decidim/pull/16666\n\n### Workarounds\n\nDisable the \"Identity documents\" verification \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-2026-45330"],"modified":"2026-07-13T17:11:53.902950Z","published":"2026-07-13T16:54:32Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-200"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-07-13T16:54:32Z"},"references":[{"type":"WEB","url":"https://github.com/decidim/decidim/security/advisories/GHSA-86fh-w43w-338c"},{"type":"WEB","url":"https://github.com/decidim/decidim/pull/16666"},{"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-86fh-w43w-338c/GHSA-86fh-w43w-338c.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-86fh-w43w-338c/GHSA-86fh-w43w-338c.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-86fh-w43w-338c/GHSA-86fh-w43w-338c.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:H/I:N/A:N"}]}
