Description

A flaw was found in HuggingFace Transformers. A remote attacker can exploit this vulnerability by supplying a specially crafted checkpoint file (e.g., `rng_state.pth`). The `_load_rng_state()` method in the `Trainer` class loads this file using `torch.load()` without proper validation, specifically missing the `weights_only=True` parameter. This issue primarily affects systems using PyTorch versions below 2.6. Successful exploitation can lead to arbitrary code execution on the system where the file is loaded.
