Summary
text-generation-webui is an open-source web interface for running Large Language Models. Prior to 4.1.1, users can save extention settings in "py" format and in the app root directory. This allows to overwrite python files, for instance the "download-model.py" file could be overwritten. Then, this python file can be triggered to get executed from "Model" menu when requesting to download a new model. This vulnerability is fixed in 4.1.1.
