{"id":"GHSA-529p-jj47-w3m3","summary":"Decidim cross-site scripting (XSS) in the admin panel","details":"### Impact\n\nThe admin panel is subject to potential XSS attach in case the attacker manages to modify some records being uploaded to the server.\n\nThe attacker is able to change  e.g. to `\u003csvg onload=alert('XSS')\u003e` if they know how to craft these requests themselves. And then enter the returned blob ID to the form inputs manually by modifying the edit page source.\n\n### Patches\n\nAvailable in versions 0.27.6 and 0.28.1.\n\n### Workarounds\n\nReview the user accounts that have access to the admin panel (i.e. general Administrators, and participatory space's Administrators) and remove access to them if they don't need it. \n\n### References\n\nOWASP ASVS v4.0.3-5.1.3\n","aliases":["CVE-2024-27095"],"modified":"2024-07-11T21:47:13.169424Z","published":"2024-07-10T16:02:07Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2024-07-10T16:02:07Z","nvd_published_at":"2024-07-10T19:15:10Z","cwe_ids":["CWE-79"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/decidim/decidim/security/advisories/GHSA-529p-jj47-w3m3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27095"},{"type":"PACKAGE","url":"https://github.com/decidim/decidim"},{"type":"WEB","url":"https://github.com/decidim/decidim/releases/tag/v0.27.6"},{"type":"WEB","url":"https://github.com/decidim/decidim/releases/tag/v0.28.1"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/decidim-admin/CVE-2024-27095.yml"}],"affected":[{"package":{"name":"decidim-admin","ecosystem":"RubyGems","purl":"pkg:gem/decidim-admin"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.27.6"}]}],"versions":["0.0.1","0.0.1.alpha3","0.0.1.alpha4","0.0.1.alpha5","0.0.1.alpha6","0.0.1.alpha7","0.0.1.alpha8","0.0.1.alpha9","0.0.2","0.0.3","0.0.5","0.0.6","0.0.7","0.0.8.1","0.1.0","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","0.2.0","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","0.27.2","0.27.3","0.27.4","0.27.5","0.3.0","0.3.1","0.3.2","0.4.0","0.4.1","0.4.2","0.4.3","0.4.4","0.5.0","0.5.1","0.6.0","0.6.1","0.6.2","0.6.3","0.6.4","0.6.5","0.6.6","0.6.7","0.6.8","0.7.0","0.7.1","0.7.2","0.7.3","0.7.4","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/2024/07/GHSA-529p-jj47-w3m3/GHSA-529p-jj47-w3m3.json"}},{"package":{"name":"decidim-admin","ecosystem":"RubyGems","purl":"pkg:gem/decidim-admin"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.28.0.rc1"},{"fixed":"0.28.1"}]}],"versions":["0.28.0","0.28.0.rc4","0.28.0.rc5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/07/GHSA-529p-jj47-w3m3/GHSA-529p-jj47-w3m3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:P/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
