Description
A Host Header Injection vulnerability exists in the password reset functionality of CraftMyCMS 4.0.2.2. The system uses `$_SERVER['HTTP_HOST']` directly to construct password reset links sent via email. An attacker can manipulate the Host header to send malicious reset links, enabling phishing attacks or account takeover.
