CVE-2026-106030 is an incorrect authorization vulnerability in NordVPN for Windows versions before 8.12. A low-privileged local attacker can impersonate a trusted process when connecting to the NordVpnService named pipe and invoke ISettingsGrpc.StopService and ISettingsGrpc.ChangeServiceStartType with arbitrary service names. These operations allow the attacker to stop unprotected Windows services and change their startup type to Manual, causing denial of service. Services protected by Protected Process Light (PPL) or Windows Tamper Protection, including Windows Defender, cannot be stopped or reconfigured through this vulnerability.
