Description
On affected EOS platforms with AAA-based gRPC authorization enabled for OpenConfig, gRPC requests of an authenticated user to OpenConfig may use the wrong privilege level, resulting in an authorization using the wrong AAA method list. This does not impact non-gRPC OpenConfig requests such as NETCONF.
