CVE-2025-14929

Code execution via unsafe X-CLIP checkpoint loading

Published Dec 23, 2025 · Updated Dec 23, 2025

Deserialization in Hugging Face Transformers X-CLIP conversion allows attackers to execute code through a malicious checkpoint. The conversion script passes downloaded checkpoint data to torch.hub.load_state_dict_from_url without restricting deserialization to weight tensors. Execution requires the target to open malicious content that triggers checkpoint conversion and occurs with the current process's privileges.
