The Content Translation module for Drupal 6.x enables users to make
a translation of an existing item of content (a node). In that proces
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unpublished nodes even if they do not have permission to view
unpublished nodes.
When user profile pictures are enabled, the default user profile
validation function will be bypassed, possibly allowing invalid user
names or e-mail addresses to be submitted.
