CVE-2026-15679

Code execution via unsafe checkpoint deserialization

Published Aug 20, 2026 · Updated Aug 20, 2026

Insecure deserialization in checkpoint parsing in Hugging Face PyTorch Image Models 1.0.24 allows attackers to execute code via crafted checkpoints. The vulnerable load_state_dict, load_checkpoint, and related helper paths passed checkpoint data to torch.load with unsafe defaults, allowing pickled objects embedded in an untrusted checkpoint to be deserialized in the running process. Exploitation requires a user or application to load attacker-supplied checkpoint content; published records describe code execution in the current process and do not show a broader privilege boundary crossing.
