Nodequeue 5.x before 5.x-2.7 and 6.x before 6.x-2.2, a module for Drupal, does not properly restrict access when displaying node titles, which has unknown impact and attack vectors.

Drupal 6.x before 6.x-2.6, a module for Drupal, allows remote authenticated users to bypass access restrictions and (1) read unpublished content from anonymous users when a view is already configured to display the content, and (2) read private content in generated queries.
