Vulnerability Details

Hugging Face Transformers Perceiver Model Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face Transformers. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of model files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-25423.

Found in base branch: main

Vulnerability Details

A vulnerability in the HuggingFace Transformers library, specifically in the "Trainer" class, allows for arbitrary code execution. The "_load_rng_state()" method in "src/transformers/trainer.py" at line 3059 calls "torch.load()" without the "weights_only=True" parameter. This issue affects all versions of the library supporting "torch>=2.2" when used with PyTorch versions below 2.6, as the "safe_globals()" context manager provides no protection in these versions. An attacker can exploit this vulnerability by supplying a malicious checkpoint file, such as "rng_state.pth", which can execute arbitrary code when loaded. The issue is resolved in version v5.0.0rc3.
