SA-CONTRIB-2015-037 - Path Breadcrumbs - Access Bypass

This module enables you to configure breadcrumbs for any Drupal page.

The module doesn’t check node access on 403 Not Found pages. As a result, unpublished content data can be shown to unprivileged user.

This vulnerability is mitigated by the fact that it is possible to configure proper access control in Path Breadcrumbs items with “Selection Rules” from the UI.
