The application leaks the password reset token within a hidden HTML input field on the password reset page. This allows any unauthenticated attacker to retrieve the reset token for any user by simply querying the user\u0027s email, leading to full Account Takeover (ATO) without requiring access to the victim\u0027s email inbox. This vulnerability is fixed in 1.6.3."
