GPT-SoVITS-WebUI is a voice conversion and text-to-speech webUI. In versions 20250228v3 and prior, there is a command injection vulnerability in the webui.py open_slice function. slice_opt_root and slice-inp-path takes user input, which is passed to the open_slice 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.
