I stumbled upon a website that i thought I could edit. Using inspect element. But it was just a temporary modification. After I refreshed the page my edited element was gone. I googled a bit and the site was protected against SQL injection. I tried only SQL injection as it was the easiest method I could find. Now I want to get some information about how can I edit those SQL protected websites (of course , from a hacker's point of view) . I want to be able to change links inside the website's database. I would greatly appreciate any reply.
