The Content Translation module for Drupal 6.x enables users to make a translation of an existing item of content (a node). In that process the existing node's content is copied into the new node's submission form.
The module contains a flaw that allows a user with the 'translate content' permission to potentially bypass normal viewing access restrictions, for example allowing the user to see the content of unpublished nodes even if they do not have permission to view unpublished nodes.
This issue only affects Drupal 6.x.
