torch is vulnerable to Remote Code Execution (RCE). The vulnerability is caused by a lack of restriction on function calls when a worker node sends a PythonUDF to the master node, which then executes the function without proper validation within the torch.distributed.rpc framework. This allows attackers to execute arbitrary commands by leveraging built-in Python functions like eval during multi-CPU RPC communication.
