How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
