Is this vulnerability exploitable by unauthenticated users?

No. The weakness resides in the customer portal and requires a valid authenticated customer account. However, any ordinary customer account may be able to exploit it against other customers if the check is missing.

What level of access does an attacker need to exploit this issue?

The attacker only needs standard customer-level access. Once logged in, they can manipulate the order ID parameter in the reorder request to target other customers' orders, assuming no additional controls are in place.

What is the safest general fix pattern for this type of vulnerability?

The most robust fix is to implement object-level authorization that ensures the referenced order is owned by the authenticated user before performing any action. All order-related operations should be guarded by centralized authorization policies that enforce ownership, rather than relying on the presence of an order ID alone.
