CVE-2026-41255

CKAN: CSRF exemption primed by anonymous requests

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.10 and 2.11.5, Access to the views via tokens or unauthenticated requests marked the endpoint as not requiring CSRF protection. The marking was a member variable in flask-wtf.csrf.CSRFProtect(), which was stored as a module level variable in the flask_app middleware. This API was never intended for request level changes, it is primarily a decorator for static configuration. An unauthenticated request could hit a protected endpoint, exempting it from CSRF protection for the life of the particular server process. (e.g. one worker of uwsgi). This vulnerability is fixed in 2.10.10 and 2.11.5.

CKAN: No certificate validation on STMP connection

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.10 and 2.11.5, the configured SMTP server may be spoofed with any certificate (e.g. self-signed), leaving credentials and all emails sent open to MITM attacks. This vulnerability is fixed in 2.10.10 and 2.11.5.

CVE-2025-64100

CKAN Vulnerable to Session Cookie Fixation

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, session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim's browser or steal the victim's currently valid session. Session identifiers are now regenerated after each login. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4

CVE-2025-54384

CKAN stored XSS vulnerability in Markdown description fields

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.

CVE-2025-24372

XSS vector in user uploaded images in group/org and user profiles in ckan

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Using a specially crafted file, a user could potentially upload a file containing code that when executed could send arbitrary requests to the server. If that file was opened by an administrator, it could lead to escalation of privileges of the original submitter or other malicious actions. Users must have been registered to the site to exploit this vulnerability. This vulnerability has been fixed in CKAN 2.10.7 and 2.11.2. Users are advised to upgrade. On versions prior to CKAN 2.10.7 and 2.11.2, site maintainers can restrict the file types supported for uploading using the `ckan.upload.user.mimetypes` / `ckan.upload.user.types` and `ckan.upload.group.mimetypes` / `ckan.upload.group.types` config options. To entirely disable file uploads users can use: `ckan.upload.user.types = none`

CVE-2024-41674

CKAN may leak Solr credentials via error message in package_search action

CKAN is an open-source data management system for powering data hubs and data portals. If there were connection issues with the Solr server, the internal Solr URL (potentially including credentials) could be leaked to package_search calls as part of the returned error message. This has been patched in CKAN 2.10.5 and 2.11.0.
