GPT-SoVITS-WebUI is a voice conversion and text-to-speech webUI. In versions 20250228v3 and prior, there is a command injection vulnerability in webui.py open_denoise function. denoise_inp_dir and denoise_opt_dir take user input, which is passed to the open_denoise function, which concatenates the user input into a command and runs it on the server, leading to arbitrary command execution. At time of publication, no known patched versions are available.
