SA-CONTRIB-2026-208: Critical severity drupal/dkan vulnerability
Published Oct 7, 2026
·Updated
The DKAN module enables organizations and individuals to build open data portals in Drupal. The DKAN datastore imports tabular data files into database tables and exposes them for querying with a JSON API. The module does not correctly check access for all of its endpoints, leading to a potential access bypass. The vulnerability is mitigated by the fact that it is only impactful for sites that do not give "access content" permission to the anonymous role.
