CVE-2025-61136Network attack vector

Account takeover via poisoned password-reset links

Published Oct 23, 2025 · Updated Oct 23, 2025

Host header injection in axewater sharewarez 2.4.3 allows remote attackers to steal password-reset tokens and take over accounts. The send_password_reset_email function calls Flask's url_for with _external=True, so an untrusted Host header supplies the authority in the emailed reset URL. The target must follow the poisoned link; the valid token is then sent to the attacker-controlled host, enabling a password change.
