How It Affects Your App
MySQL 1131 ER_PASSWORD_ANONYMOUS_USER indicates that an anonymous user is attempting to access the database without a valid password. This can have a significant impact on the application as it can lead to unauthorized access to sensitive data, or even malicious activities such as data manipulation or deletion. It can also lead to a decrease in performance due to the increased load on the database server. Furthermore, it can lead to a decrease in security as the anonymous user can bypass authentication and authorization mechanisms.
