CVE-2025-27778Network attack vector

Unauthenticated code execution via unsafe model loading

Published Mar 19, 2025 · Updated Mar 20, 2025

Unsafe deserialization in AI Hispano Applio 3.2.8-bugfix and earlier allows remote attackers to execute code via a model path. The inference and text-to-speech interfaces pass a user-controlled model_file path through get_vc, which calls torch.load without weights_only=True in rvc/infer/infer.py. An unauthenticated network user who can supply a malicious PyTorch model path gains code execution with the Applio server process's privileges.
