The JetFormBuilder WordPress plugin before 3.6.5.2 does not validate or strip line breaks from address values it sources from submitted form fields before adding them to the headers of the e-mails it sends, allowing unauthenticated users to inject arbitrary e-mail headers, add hidden recipients and spoof the sender. Exploitation requires the site to be configured to take one of the message's addresses from a form field.
