Technical details
The vulnerability is an Email Header Injection (CWE-640) within the Login/Register widget of the Essential Addons for Elementor plugin. The root cause is insufficient server-side validation and sanitization of widget settings used to construct outgoing email headers; specifically, the plugin fails to strip or encode Carriage Return/Line Feed (CRLF) characters. An authenticated attacker with Contributor-level permissions or higher can inject a 'Bcc' header into the administrator's password-reset notification. This allows the attacker to receive a copy of the valid reset link, leading to full account takeover. The issue is addressed in version 6.6.11.
