| Descrição | The server is supposed to serve Markdown templates from its bundled templates directory. Instead, both exported tools construct filenames from untrusted language input and pass them into read_template():
get_style_guide(language) builds f"{language}_style_guide.md"
get_best_practices(language) builds f"{language}_best_practices.md"
read_template() then does os.path.join(os.path.dirname(__file__), "templates", filename) and opens the resulting path directly. Because neither the input nor the resolved path is validated, traversal strings such as ../../../../tmp/secret escape templates/ and read files like /tmp/secret_style_guide.md. |
