Description

Requirements:
  • Have images in a file-storage somewhere
  • Create a text-with-image content and add that image
  • Edit that content with a user with limited rights
    • Make sure that user only has filemounts so that he/she can't access the above added image
    • User should have access to sys_file_metadata and sys_file_reference
Situation:
  • Image is shown in the content-element
  • File-metadata can be overridden (sys_file_reference)
  • But clicking the edit-icon the original metadata for that file cannot be edited because the file is outside of allowed filemounts

Currently only a very generic error is shown:
"Access to table sys_file_metadata for user 2 was denied by a makeEditForm_accessCheck hook"
(which is an AccessDeniedHookException)

How specific could we be in this case? I assume we may not disclose the original path the user does not have access to. So maybe just some "That file is outside of the allowed filemounts for this user"?
