Explanation
Moving validation controls from the server side into the browser would most likely increase the risk of a successful attack by structured query language (SQL) injection. SQL injection is a technique that exploits a security vulnerability in an application's database layer by inserting malicious SQL statements into user input fields. Validation controls are used to check and filter user input before sending it to the database. If these controls are moved to the browser, they can be easily bypassed or modified by an attacker, who can then execute arbitrary SQL commands on the database.
