What they could let someone do.

What could happen

  • Server side request forgery

    Someone could make your server fetch addresses for them, reaching services that are meant to be private.

    How: The software fetches an address it was sent without checking where it points.

  • Cross-site scripting

    Someone could make your pages run their own script in visitors' browsers, to steal logins, show a fake payment form or send people to a scam site.

    How: The software puts text it was sent back onto a page without making it safe first, so a script hidden in a link, form or comment runs as if it were part of your site.
