What is CVE-2026-0673?

The Element Pack Addons for Elementor plugin for WordPress contains a security flaw that allows for Email Header Injection. This flaw, present in all versions up to and including 8.3.15, stems from inadequate sanitization of newline characters in user input, particularly during the handling of the element_pack_contact_form AJAX action. As a result, unauthenticated attackers can exploit this vulnerability to insert arbitrary email headers, potentially leading to malicious actions or unauthorized data exposure through email communications sent by the contact form.
