PyTorch: `torch.load` with `weights_only=True` leads to remote code execution
Packages
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.

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.
