The CCK 1.6 releases for the 4.7 and 5 branches fix two XSS (Cross Site Scripting) vulnerabilities in nodereference.module.
All sites using CCK / nodereference.module should consider upgrading to this release as soon as possible.
Security announcement: DRUPAL-SA-2007-019
The release also fixes some (less critical) bugs. Main new feature is the additional 'full node / teaser' formatters for nodereference.
See release notes for more info.
