Why get_asset_url is rated Low

It performs a query-like operation with no side effects, no data modification, no code execution, and no irreversible changes. The 'signed' URL mechanism is standard for secure but read-only access. Severity is low because misuse would only expose already-existing assets, not compromise system integrity or enable destructive actions.
