title: Can an attacker use inspect element harmfully?
body: <p>I know this is a broad question, but I think I'm missing something here. Is it possible for an attacker to cause damage to a site by simple using inspect element and editing the javascript and html? For example, it seems too easy for someone to change the maxlength of an input, and upload so much data that it could crash the server, I know that it is always good practice to check data at the server but it still seems too easy. Or another more potentially dangerous example is if the attacker can mess with an <code>$.ajax</code> call and send bad info to the server. Is it something I should be worrying more about or are the changes just temporary, on the attackers browser?</p>
