Because the vulnerability requires only access to the exposed OData endpoints, an attacker could exploit it from any network segment that can reach those services, assuming no authentication checks are in place. Although the impact on confidentiality and availability is minimal, the ability to alter or delete data could disrupt business processes, warranting prompt attention.
