CVE-2025-49837Network attack vector

Unauthenticated code execution via unsafe model deserialization

Published Jul 15, 2025 · Updated Jul 16, 2025

Unsafe deserialization in RVC-Boss GPT-SoVITS 20250228v3 and earlier allows remote attackers to execute code through a model path. The vr.py AudioPre constructor passes the user-controlled model_path directly to torch.load after appending .pth, permitting pickle payload execution. The WebUI exposes model_choose without authentication, so network access to the interface is sufficient for code execution under the service account.
