10.5 Database Security

SQL injection attacks remain one of the most common security vulnerabilities in web applications. We prevent these attacks by using prepared statements and parameterized queries consistently, never building SQL queries through string concatenation.

WordPress provides the $wpdb->prepare() method for safely constructing database queries. We use this method whenever we need to include user input in database queries.

Laravel’s Eloquent ORM and query builder automatically protect against SQL injection when used properly. We use parameter binding for raw queries and leverage Eloquent’s built-in protection for most database operations.
