A path traversal vulnerability exists in the parisneo/lollms-webui repository, specifically in the "lollms_file_system.py" file. The functions "add_rag_database", "toggle_mount_rag_database", and "vectorize_folder" do not implement security measures such as "sanitize_path_from_endpoint" or "sanitize_path". This allows an attacker to perform vectorize operations on ".sqlite" files in any directory on the victim's computer, potentially installing multiple packages and causing a crash.
