CVE-2025-61132Network attack vector

Account takeover via Host-derived password-reset links

Published Oct 23, 2025 · Updated Oct 23, 2025

Host header injection in levlaz braindump 0.4.14 allows remote attackers to poison password-reset links and take over accounts. The reset_password email template calls Flask url_for with _external=True, causing an unvalidated request Host header to determine the absolute reset URL. The attack requires Host-header control during a reset request and the recipient to follow the poisoned link, exposing the token to the attacker-controlled domain.
