reading of cross origin images isn't an attack vector unless credentials were used to request it.

- bgirard 6y agoYou're a bit too quick to jump to that conclusion so firmly. There are other cases. Does you company have internal tools exposed via the intranet? If you happen to know the URI scheme, from say an ex-employee, you're able to exfiltrate information if you get a current employee on VPN to open your page. This becomes a tool in a layered attack. Sure it's careless to have such anonymous endpoint on your intranet. But there's a reason why anonymous images can't be plainly read back.
