GPT-SoVITS (a voice synthesis tool) version 20250606v2pro has an OS command injection vulnerability (a security flaw where attackers can run unauthorized commands on a server by inserting malicious text) in its webui.py file. The vulnerability affects ASR, slice, denoise, and uvr5 functions that take user input from Gradio textboxes (input fields in a web interface) and directly insert it into shell commands without checking for dangerous characters, allowing attackers to execute arbitrary commands without authentication.
