- Advisory ID: DRUPAL-SA-CONTRIB-2010-088
- Project: Content Construction Kit (CCK) (third-party module)
- Version: 6.x
- Date: 2010-August-11
- Security risk: Less Critical
- Exploitable from: Remote
- Vulnerability: Access Bypass
The Content Construction Kit (CCK) project is a set of modules that allows you to add custom fields to nodes using a web browser.
The CCK "Node Reference" module provides a backend URL that is used for asynchronous requests by the "autocomplete" widget to locate nodes the user can reference. In some cases, this was not correctly checking that the user had field level access to the source field, allowing direct queries to the backend URL to return node titles and IDs which the user would otherwise be unable to access. Note that as Drupal 5 CCK does not have any field access control functionality, this issue only applies to the Drupal 6 version.
This advisory is a follow-up related to advisory SA-CONTRIB-2010-065.
