Question: Suppose we encrypt two multi - block messages with CBC mode but use the same IV each time. What information about the plaintext is leaked

Suppose we encrypt two multi-block messages with CBC mode but use the same IV each time.
What information about the plaintext is leaked by the ciphertext? (You also might try to imagine a
scenario in which this information is useful to an attacker.
