To be vulnerable to CVE-2026-2380, any of the following configurations must be present:
With any of these servers enabled, the OpenConfig/Octa agent can log sensitive information in the local log file.
gNMI server enabled:

RESTCONF server enabled:
#show running-config section restconf\nmanagement api restconf\n transport https default\n ssl profile mySslProfile
NETCONF server enabled:
#show running-config section netconf\nmanagement api netconf\n transport ssh default
In addition to local logging, sensitive information may be recorded on remote accounting servers if any of the following configurations are present:
gRPC AAA accounting sensitive logging (for gNMI only):
#show running-config section gnmi\nmanagement api gnmi\n transport grpc default\n accounting requests
gNSI.Acctz accounting sensitive logging (for gNMI only):
#show running-config section gnmi\nmanagement api gnmi\n transport grpc default\n#show running-config section gnsi\nmanagement api gnsi\n service acctz
