CKAN stored XSS vulnerability in Markdown description fields_CVE-2025-54384

6.3 / 10

MEDIUM

CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N

Description

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. 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.
