In a symmetric encryption scheme built using the ECB mode of operation, the key generation algorithm is used to randomly pick a key from the keyspace for every new block of the message that has to be encrypted 

Since the encryption scheme is publicly available, in an IND-CPA experiment, an attacker is able to compute ciphertexts for their chosen message without consulting the oracle.
