Overview
Affected versions of this package are vulnerable to Missing Authorization in the 3gpp-traffic-influence API route group, which lacks inbound authorization checks. An attacker can create, read, modify, or delete traffic-influence subscriptions by sending unauthenticated or forged requests to the exposed endpoints. This allows unauthorized parties to manipulate traffic-steering policies, leak sensitive configuration data, and disrupt legitimate service operations. This is only exploitable if the attacker can reach the NEF service on the SBI network, regardless of the configured ServiceList.
