Is SQL Injection Protection Necessary for Dropdown Inputs?

Do I need SQL injection protection with dropdown inputs?

Question:

Despite being aware of the need to prevent SQL injection with user input, is it still necessary to guard against it if all user input is limited to dropdown selections?

Answer:

Absolutely yes. While limiting input options via dropdowns may seem like a safeguard, it's crucial to remember that:

• Users can manipulate values: Web browsers allow users to edit dropdown options, potentially injecting malicious code that could still harm your database.
• External requests can bypass client-side restrictions: Tools like cURL enable users to send arbitrary HTTP requests and bypass any form submission restrictions.
• NEVER trust user input: Regardless of the input method, always assume it can be malicious and protect your database accordingly.

Therefore, it is essential to implement SQL injection protection measures on all input, including dropdown selections, to protect your database from potential harm.
