How broadly exploitable is this vulnerability?

Exploitability depends on how widely the `/api/food/{id}/shopping/` endpoint is exposed and how many tenants share the same deployment. Any authenticated user who can add items to a shopping list can attempt to reference units from other Spaces or send malformed `amount` values.

Does an attacker need special privileges to exploit it?

Typically, no elevated privileges are needed beyond the ability to call the shopping list creation endpoint. However, they must already be able to authenticate or otherwise access the API in a way that the application recognizes them as a user within a Space.

What is the safest general fix pattern?

Route all object creation through a shared serializer or validation layer that enforces type and range constraints for `amount` and strictly verifies that foreign keys like `unit` belong to the caller's Space. Treat validation failures as client errors and never rely on the database layer to surface them safely.
