{"id":"CVE-2024-47819","aliases":["GHSA-c5g6-6xf7-qxp3"],"url":"https://o3.security/vulnerability/CVE-2024-47819","summary":"Umbraco CMS vulnerable to stored Cross-site Scripting in the \"dictionary name\" on Dictionary section","details":"Umbraco, a free and open source .NET content management system, has a cross-site scripting vulnerability starting in version 14.0.0 and prior to versions 14.3.1 and 15.0.0. This can be leveraged to gain access to higher-privilege endpoints, e.g. if you get a user with admin privileges to run the code, you can potentially elevate all users and grant them admin privileges or access protected content. Versions 14.3.1 and 15.0.0 contain a patch. As a workaround, ensure that access to the Dictionary section is only granted to trusted users.","published":"2024-10-22T15:25:03.501Z","modified":"2026-07-15T01:49:18.868114651Z","cvss":{"score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@umbraco-cms/backoffice","fixedVersion":"14.3.1"},{"ecosystem":"NuGet","name":"Umbraco.Cms.StaticAssets","fixedVersion":"14.3.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47819.json"},{"type":"ADVISORY","url":"https://github.com/umbraco/Umbraco-CMS/security/advisories/GHSA-c5g6-6xf7-qxp3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47819"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:18.868114651Z"}}
