Description
The Email Before Download plugin for WordPress is vulnerable to SMTP Header Injection in versions up to, and including, 3.6 via the 'email_from' POST parameter, where the 'emailfrom' variable is concatenated in the SMTP 'From:' header and then directly passed to wp_mail. This makes it possible for unauthenticated attackers to add newline characters which can lead to arbitrary headers/message bodies.
