CVE-2025-61541Network attack vector

Account takeover via poisoned password-reset links

Published Oct 16, 2025 · Updated Oct 16, 2025

Host header injection in Webmin 2.510 and earlier allows remote attackers to poison password-reset links sent by email. forgot_send.cgi calls get_webmin_email_url(), which trusts the attacker-controlled HTTP Host header when forming the reset URL. The password-reset feature must be enabled and a recipient must follow the poisoned link, exposing the reset token and permitting takeover of that account.
