The Forward module is a module that allows site administrators to add links to postings that let users email the current page to a third party. By manipulating URL arguments, authenticated and anonymous users are able to access posts that should have been restricted by a node access module such as Organic Groups, Taxonomy Access Control, Taxonomy Access Lite, etc.

Versions affected

  • Forward for Drupal 5.x before 5.x-1.0
  • Forward for Drupal 4.7.x before 4.7-1.1
