CVE-2024-3568Public exploitNetwork attack vector

Code execution via untrusted checkpoint deserialization

Published Apr 10, 2024 · Updated Aug 1, 2024

Code execution in Hugging Face Transformers before 4.38.0 allows remote attackers to run commands through a malicious checkpoint. The TFPreTrainedModel.load_repo_checkpoint method passes checkpoint/extra_data.pickle directly to pickle.load without validating its source or contents. Exploitation requires a victim to load an attacker-supplied checkpoint during TensorFlow model training, after which the payload runs with the victim process's privileges.
