我正在为我的 web 应用程序编写一个辅助函数，该函数根据从外部 API（不是用户输入的）获取的一些信息来更新数据库。我有以下代码，但它被 Bandit python 包标记为“不安全”。

理想情况下，我可以以硬编码要更新的列的方式编写一个函数，但我认为它也应该可以动态实现。

这是更新表的安全方法（不可能进行 SQL 注入）吗？

import mysql.connector as database

def update_message_by_uid(uid: str, update_dict: dict) -> None:

    # Fetches the previous entry from the database using the unique identifier
    message_info_dict = get_message_by_uid(uid)

    # check that all the keys of the update dict are also in the original dict
    assert set(update_dict.keys()) <= set(
        message_info_dict.keys()
    ), "Some of the keys in the dictionary passed are not valid database columns"

    # We update the entry for all entries in the dictionary containing the updates
    statement = 'UPDATE messages SET {}  WHERE uid = %s'.format(", ".join('{}=%s'.format(k) for k in update_dict))


    # Concatenates the values of the dict with the unique identifier to pass it to the execution method as one variable
    data = list(update_dict.values()) + [uid]

    cursor.execute(statement, data)
