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.
