Kali Forms < 2.4.30 - Subscriber+ User Email Address Disclosure

The Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.30 does not perform a capability check when its test-email handler resolves and returns a user's email address, relying only on a nonce that is available to any logged-in user, allowing authenticated users with minimal privileges (Subscriber and above) to disclose the email address of any registered user, including administrators.
