CVE-2025-13710

Root code execution via unsafe VAE deserialization

Published Dec 23, 2025 · Updated Dec 23, 2025

Deserialization in Tencent HunyuanVideo Current allows remote attackers to execute arbitrary code through a crafted VAE checkpoint. The load_vae function passes pytorch_model.pt data to torch.load without validating its serialized objects, allowing attacker-controlled code to run. Exploitation requires a user to open the malicious file or visit a page that supplies it, and successful code runs with the application's root privileges.
