Description
2FAuth before 9.0.1 contains a weak password recovery vulnerability that allows unauthenticated attackers to poison reset links by forging the HTTP Host header. Attackers can request password or WebAuthn recovery emails with an attacker-controlled host, capture the victim's token, and take over accounts exposing stored TOTP/HOTP secrets.
