The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

The product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.

Remediation

Update to version 4.5.4, or a newer patched version

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. None of that substitutes for the fix: WP Easy Pay 4.5.4 closes this, and updating the plugin is the step that ends it.
