TorchServe gRPC Port Exposure

### Impact The two gRPC ports 7070 and 7071, are not bound to [localhost](http://localhost/) by default, so when TorchServe is launched, these two interfaces are bound to all interfaces. Customers using PyTorch inference Deep Learning Containers (DLC) through Amazon SageMaker and EKS are not affected. ### Patches This issue in TorchServe has been fixed in [#3083](https://github.com/pytorch/serve/pull/3083). TorchServe release 0.11.0 includes the fix to address this vulnerability. ### References * [#3083](https://github.com/pytorch/serve/pull/3083) * [TorchServe release v0.11.0](https://github.com/pytorch/serve/releases/tag/v0.11.0) Thank Kroll Cyber Risk for for responsibly disclosing this issue.
