CVE-2026-63766Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized path fields

Published Jul 20, 2026 · Updated Jul 20, 2026

OS command injection in RVC-Boss GPT-SoVITS through 20250606v2pro allows remote attackers to execute commands through path fields. ASR, slice, denoise, and uvr5 code in webui.py interpolates Gradio textbox values into command strings passed to Popen with shell=True. The WebUI listens on all interfaces without authentication, so reachable attackers execute commands with the server process user's access.
