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.
Risk Assessment
The risk includes potential use of the contact form to send spam or phishing emails, which could harm the organization's reputation and expose users to attacks.
Recommendation
Update the Element Pack Addons plugin to the latest version that contains the fix. Also consider adding additional input validation.
