The patches indicate that the vulnerability is related to the deserialization of 'com.zaxxer.hikari.HikariConfig' and its subclasses. The mitigation involves adding these classes to a blacklist, suggesting that the deserialization process is the vulnerable component. The exact function name might vary based on the exact method handling the deserialization check, but it's related to the SubTypeValidator class.
