Overview
Affected versions of this package are vulnerable to Missing Authorization in the nnef-oam route group due to missing inbound authentication and authorization checks. An attacker can gain unauthorized access to administrative operations by sending unauthenticated requests to the exposed endpoints. This is only exploitable if the NEF instance is accessible on the SBI interface without additional network restrictions.
