In app/controllers/users_controllers.rb at line 3, the current code directlyinterpolates user input into the SQL query, causing a SQL injectionvulnerability. To fix this, replace the string interpolation with aparameterized query by using a placeholder and passing params[:email] as aseparate argument, like User.where("email = ?", params[:email]). This changeensures safe query execution by properly escaping user input.

In app/controllers/users_controllers.rb lines 1 to 5, rename the file tousers_controller.rb to follow Rails naming conventions and avoid autoloadingissues. Add an authorization callback such as before_action :authenticate_user!or after_action :verify_authorized to secure the controller. Modify the indexaction to use parameterized queries (e.g., User.where(email: params[:email])) toprevent SQL injection, and add pagination using a gem like Kaminari by chaining.page(params[:page]).per(params[:per_page] || 25) to limit result sets.
