CVE-2026-0673Network attack vectorHinoki check available

Unauthenticated email header injection via newline concatenation

Published Aug 6, 2026 · Updated Aug 6, 2026

Email header injection in BdThemes Element Pack Addons for Elementor 8.3.15 and earlier allows remote attackers to add arbitrary email headers. The element_pack_contact_form AJAX action concatenates user-supplied values containing newline characters into outbound email headers without sufficient sanitization. No authentication or user interaction is required, and the resulting control is limited to headers on messages sent through the plugin's contact form.
