Featured Image from URL < 4.0.0 - Arbitrary Settings Update to Stored XSS via CSRF

The plugin does not have CSRF check in place when updating its settings, which could allow attackers to make a logged in admin change them via a CSRF attack. Furthermore, due to the lack of validation, sanitisation and escaping in some of them, it could also lead to Stored XSS issues

PoC

All settings appear to be affected. The XSS will be triggered when accessing the settings again
