Upstream source description

The Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.30 does not perform a capability check on its test-email handler, relying only on a nonce that is available to any logged-in user, so a low-privileged user such as a Subscriber can make the site send email to an arbitrary recipient with a spoofed sender address.
