Path Traversal in MetaGPT SPO Extension

Executive Summary

This is a path traversal vulnerability in MetaGPT 0.8.1's SPO extension. It allows an attacker to read arbitrary files by manipulating the FILE_NAME value used in set_file_name() and load_meta_data() functions. The issue occurs because the code combines the attacker-controlled FILE_NAME with the settings directory and opens the path without checking if it stays within the intended directory.
