Details

Summary

A user with no view rights on a page may see the content of an office attachment displayed with the view file macro.

  3. Add an attachment to the restricted page
  4. Create a new public page
  5. Add the view file macro and select the attachment from the restricted page using any display type
  6. Login as the test user with restricted view rights
  7. The user will see the content despite having no view rights
