AI-suggested
A fixed version 9.0.1 of Bubka 2FAuth is available that addresses this vulnerability. Users and administrators should upgrade to version 9.0.1 or later to remediate this issue. No additional mitigation steps are indicated beyond applying the official fix.
Description
Bubka 2FAuth versions before 9.0.1 have a weak password recovery mechanism that allows unauthenticated attackers to manipulate password reset links via the HTTP Host header. This vulnerability enables attackers to request recovery emails with attacker-controlled hosts, potentially capturing victim tokens and taking over accounts with stored TOTP/HOTP secrets.
