# Security Policy

## Hugging Face Hub, remote artefacts, and remote code
|
|
|
|
Transformers is open-source software that is tightly coupled to the Hugging Face Hub. While you have the ability to use it
|
|
offline with pre-downloaded model weights, it provides a very simple way to download, use, and manage models locally.
|
|
|
|
When downloading artefacts that have been uploaded by others on any platform, you expose yourself to risks. Please
|
|
read below for the security recommendations in order to keep your runtime and local environment safe.
|
|
|
|
### Remote artefacts
|
|
|
|
Models uploaded on the Hugging Face Hub come in different formats. We heavily recommend uploading and downloading
|
|
models in the [`safetensors`](https://github.com/huggingface/safetensors) format (which is the default prioritized
|
|
by the transformers library), as developed specifically to prevent arbitrary code execution on your system.
|
|
|
|
To avoid loading models from unsafe formats (e.g. [pickle](https://docs.python.org/3/library/pickle.html), you should use the `use_safetensors` parameter. If doing so, in the event that no .safetensors file is present, transformers will error when loading the model.
|
|
|
|
### Remote code
|
|
|
|
#### Modeling
|
|
|
|
Transformers supports many model architectures, but is also the bridge between your Python runtime and models that
|
|
are stored in model repositories on the Hugging Face Hub.
|
|
|
|
These models require the `trust_remote_code=True` parameter to be set when using them; please **always** verify
|
|
the content of the modeling files when using this argument. We recommend setting a revision in order to ensure you
|
|
protect yourself from updates on the repository.
|

## Reporting a Vulnerability
|
|
|
|
Feel free to submit vulnerability reports to [security@huggingface.co](mailto:security@huggingface.co), where someone from the HF security team will review and recommend next steps. If reporting a vulnerability specific to open source, please note [Huntr](https://huntr.com) is a vulnerability disclosure program for open source software.
