Prior to 2.10.9 and 2.11.4, the helpers.markdown_extract() function did not perform sufficient sanitization of input data before wrapping in an HTML literal element. This helper is used to render user-provided data on dataset, resource, organization or group pages (plus any page provided by an extension that used that helper function), leading to a potential XSS vector. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4.","published":"2025-10-29T15:26:38.426Z","modified":"2026-07-15T01:48:53.446073469Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"ckan","fixedVersion":"2.11.4"},{"ecosystem":"PyPI","name":"ckan","fixedVersion":"2.10.9"}],"fix":{"url":"https://github.com/ckan/ckan/commit/6d0065f2fc7e2682196d125275af34b93e9e554e","label":"ckan/ckan@6d0065f"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/54xxx/CVE-2025-54384.json"},{"type":"ADVISORY","url":"https://github.com/ckan/ckan/security/advisories/GHSA-2r4h-8jxv-w2j8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-54384"},{"type":"FIX","url":"https://github.com/ckan/ckan/commit/6d0065f2fc7e2682196d125275af34b93e9e554e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:53.446073469Z"}}
