I have been learning a lot by studying the questions and answers here on crypto.stackexchange.com and an grateful for this community.
Recently in this question AES in CBC Mode Is totally unsecure if no defense is provided for padding oracle attack, right? I learned that CBC is secure against chosen plaintext attacks even though it isn't secure (by itself) against chosen ciphertexts attacks or padding oracles attacks. That makes sense to me.
From what I have learned so far, I would think that there are no cases where using a CBC encryption mode would be wise unless it were paired with some kind of authentication algorithm like HMAC. But from the answers for the linked question above I get the impression that perhaps that's not true, and there are cases where such use might be reasonable.
What is a specific example of where using CBC mode encryption (ex. AES-CBC) without pairing it with validation would be an appropriate and reasonable choice?
