CVE-2023-47108

OpenTelemetry-Go Contrib is a collection of third-party packages for
OpenTelemetry-Go. Prior to version 0.46.0, the grpc Unary Server
Interceptor out of the box adds labels net.peer.sock.addr and
net.peer.sock.port that have unbound cardinality. It leads to the
server’s potential memory exhaustion when many malicious requests are sent.
An attacker can easily flood the peer address and port for requests.
Version 0.46.0 contains a fix for this issue. As a workaround to stop being
affected, a view removing the attributes can be used. The other possibility
is to disable grpc metrics instrumentation by passing
otelgrpc.WithMeterProvider option with noop.NewMeterProvider.
