Horovod versions up to and including v0.28.1 are vulnerable to unauthenticated remote code execution. The vulnerability is due to improper handling of base64-encoded data in the ElasticRendezvousHandler, a subclass of KVStoreHandler. Specifically, the put value method in ElasticRendezvousHandler calls codec.loads base64(value), which eventually invokes cloudpickle.loads(decoded). This allows an attacker to send a malicious pickle object via a PUT request, leading to arbitrary code execution on the server.
