What are the marital secrets that spouses should not discuss in front of others?

The ruling on disclosing matters of intimacy between spouses has been previously explained. As for disclosing other secrets, it is impermissible if it leads to harm or if one of the spouses requests confidentiality, based on the Prophet’s (peace and blessings be upon him) saying: "When a man speaks a word then looks around, it is a trust." Scholars have stipulated the prohibition of disclosing secrets, especially if doing so is harmful.
