What is the ruling on a wife receiving her female neighbor in the house without her husband's knowledge, especially when the husband has previously reminded his wife not to let anyone into the house except with his knowledge, and what is the appropriate action to take with the wife in this situation?

A woman is not permitted to allow anyone into her husband's house without his permission, due to what has been authentically reported from the Prophet, peace and blessings be upon him: "And you have a right over them that they should not allow anyone you dislike to sit on your beds." The husband should admonish his wife and explain to her the obligation of obeying him in what is good, and his right to prevent her from granting permission to anyone to enter his house.
