The Estatik Real Estate Plugin WordPress plugin before 4.3.4 does not validate the same recipient list that it later uses to address the message sent by its property request form, allowing unauthenticated users to send emails to arbitrary recipients with arbitrary subject, body and Reply-To on sites where the form is configured to route to a custom address.
