{"id":"CVE-2026-40321","summary":"DotNetNuke.Core has stored cross-site-scripting (XSS) via SVG upload","details":"DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.2.2, a user could upload a specially crafted SVG file that could include scripts that can target both authenticated and unauthenticated DNN users. The impact is increased if the scripts are run by a power user. Version 10.2.2 patches the issue.","aliases":["GHSA-ffq7-898w-9jc4"],"modified":"2026-07-08T08:13:12.343564682Z","published":"2026-04-17T21:10:33.192Z","database_specific":{"cwe_ids":["CWE-87"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40321.json"},"references":[{"type":"WEB","url":"https://github.com/dnnsoftware/Dnn.Platform/releases/tag/v10.2.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40321.json"},{"type":"ADVISORY","url":"https://github.com/dnnsoftware/Dnn.Platform/security/advisories/GHSA-ffq7-898w-9jc4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40321"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dnnsoftware/dnn.platform","events":[{"introduced":"0"},{"fixed":"3620738b4994107135057a1a234ff15132b19732"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:dnnsoftware:dotnetnuke:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"10.2.2"}]}}],"versions":["v10.2.1","v10.2.0","v10.1.2","v10.1.1","v10.1.0","v10.0.1","v10.0.0","v9.13.8","v9.13.7","v9.13.6","v9.13.5","v9.13.4","v9.13.3","v9.13.2","v9.13.1","v9.13.0","v9.12.0","v9.11.1","v9.11.0","v9.10.2","v9.10.1","v9.10.0","v9.9.1","v9.9.0","v9.8.1","v9.8.0","v9.7.2","v9.7.1","v9.7.0","v9.6.2","v9.6.1","v9.6.0","v9.5.0","v9.5.0-rc2","v9.4.4","v9.4.3-rc1","v9.4.3","v9.4.2","v9.4.2-rc1","v9.4.1-rc1","v9.4.1","v9.4.0","v9.4.0-rc1","v9.4.0-rc0","v9.3.0-rc1","v9.3.0-rc0","v9.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40321.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H"}]}
