Security Vulnerability in Ajax Callback Breakpoints

Imagine I have the following code snippet (partially pseudocode)

$.ajax({
    url: "/api/user",
    success: function(resp) {
        var data = JSON(resp)
        if (data.user.is_admin)
            // do admin thing
        else 
            // do something else
    }
});

Essentially, the endpoint provides user information and the callback function takes care of the rest. Is it feasible for me to set a breakpoint before the if statement, alter `data.user.is_admin` to true, and then execute the statement? Can this be done?

Answer №1

Without a doubt, it is entirely feasible. Relying on client-side code for security checks is a risky move as it can easily be manipulated using basic tools like browser developer tools.

The best practice is to have such logic implemented on the server side. It may seem limiting, but it's the only way to ensure security and keep your data safe.
