Details

As written in the advisory (Markdown source, shown as plain text).

# 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()` with `weights_only=True` to be safe. ![image](https://github.com/user-attachments/assets/fdaa8520-d66a-473a-ab1f-163d793de298) Since everyone knows that weights_only=False is unsafe, so they will use the weights_only=True to mitigate the seucirty issue. But now, I just proved that even if you use weights_only=True, it can still achieve RCE. # Credit This vulnerability was found by Ji'an Zhou.
