As the referrer is very often disabled in browsers one should IMHO rather rely on the origin header to prevent such kind of attack (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Origin). AFAIK the origin header cannot be disabled (https://www.sjoerdlangkemper.nl/2019/02/27/prevent-csrf-with-the-origin-http-request-header/)

> The COPY method , by default, is not in the list of methods covered by the CSRF Referer filter. This might allow an attacker to copy files (abusing the privileges of a logged in victim) using CSRF.
