CVE-2025-53002Public exploitNetwork attack vector

Authenticated code execution via unsafe checkpoint deserialization

Published Jun 26, 2025 · Updated Jun 26, 2025

Code injection in hiyouga LlamaFactory 0.9.3 and earlier allows remote authenticated users to execute arbitrary code through its WebUI. During reward-model training, load_valuehead_params retrieves value_head.bin from the supplied checkpoint repository and passes it to torch.load without weights_only=True. Exploitation requires WebUI access and an attacker-controlled checkpoint path, and code runs with the LlamaFactory server process's privileges.
