Detailed vulnerability description
The vulnerability allows a remote user to disclose sensitive information and modify file placement.
The vulnerability exists due to authorization bypass through user-controlled key in modules/documents-files.php move_save handling and File::moveToFolder() when processing mismatched folder_uuid and file_uuid parameters during file move requests. A remote user can submit a crafted move request to disclose sensitive information and modify file placement.
