A vulnerability in the parisneo/lollms-webui allows for arbitrary file upload and read due to insufficient sanitization of user-supplied input. Specifically, the issue resides in the install_model() function within lollms_core/lollms/binding.py, where the application fails to properly sanitize the file:// protocol and other inputs, leading to arbitrary read and upload capabilities. Attackers can exploit this vulnerability by manipulating the path and variant_name parameters to achieve path traversal, allowing for the reading of arbitrary files and uploading files to arbitrary locations on the server. This vulnerability affects the latest version of parisneo/lollms-webui.
