summary: CKAN vulnerable to stored XSS in resource description
details: "### Impact\n\nThe `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.\n\n### Patches\nThis vulnerability has been fixed in CKAN 2.10.9 and 2.11.4"
