Documize Community: Attachment Download Authorization Bypass via Non-Validated secure Token

Documize Community's attachment download route (domain/attachment/endpoint.go, Download function, registered via AddPublic with no auth middleware) accepts a `secure` query parameter and grants access whenever the parameter is simply non-empty (len(secureToken) > 0), without comparing it to any server-stored value. Any non-empty string, such as ?secure=x, bypasses authentication entirely and allows downloading any organization's attachments. Sibling handlers in the same file (togglePublish, delete) correctly enforce session-based authorization, confirming this is an inconsistency rather than intended design.
