- Summary
- PyTorch: `torch.load` with `weights_only=True` leads to remote code execution
- Details
-
Description
I found a Remote Command Execution (RCE) vulnerability in PyTorch. When loading model using torch.load with weights_only=True, it can still achieve RCE.
Background knowledge
https://github.com/pytorch/pytorch/security As you can see, the PyTorch official documentation considers using
torch.load()withweights_only=Trueto be safe.Since everyone knows that weightsonly=False is unsafe, so they will use the weightsonly=True to mitigate the seucirty issue. But now, I just proved that even if you use weights_only=True, it can still achieve RCE.
