Summary
The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Email Header Injection in all versions up to, and including, 8.3.15 via the `element_pack_contact_form` AJAX action. This is due to insufficient sanitization of newline characters in user-supplied input that gets concatenated into email headers. This makes it possible for unauthenticated attackers to inject arbitrary email headers into emails sent by the contact form.
