Summary
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, leading to a potential XSS vector.
Risk Assessment
An attacker can inject malicious JavaScript that executes in the browser of a user visiting the page, potentially leading to session theft or other attacks. The risk affects CKAN instances before versions 2.10.9 and 2.11.4.
Recommendation
Update CKAN to version 2.10.9 or 2.11.4 (or later). In the meantime, consider restricting user input capabilities.
Other vulnerabilities in CKAN
See all- CVE-2026-41132High
CKAN is an open-source data management system that, prior to versions 2.10.10 and 2.11.5, had a vulnerability allowing SMTP server spoofing. This could enable MITM attacks, exposing credentials and all sent emails.
- CVE-2025-64100Medium
CKAN is an open-source DMS for data hubs and portals. Prior to 2.10.9 and 2.11.4, session IDs could be fixed by an attacker if the site uses server-side session storage (CKAN uses cookie-based storage by default). The attacker would need to set a cookie on the victim's browser or steal a valid session. Session identifiers are now regenerated after each login.
Original NVD description (English source)
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.
