Technical details
Rodauth before 2.47.0 contains an open redirect vulnerability in the confirm_password, login_return_to_requested_location, and two_factor_auth_return_to_requested_location features. The vulnerability stems from inadequate validation of protocol-relative paths (starting with //), which browsers interpret as URLs that adopt the current page's protocol. Attackers can craft return-to paths with leading double slashes to redirect authenticated users to attacker-controlled domains after successful authentication. The vulnerability requires no special privileges and is network-reachable; the victim must authenticate and be redirected. A fix was released in version 2.47.0 with new configuration methods (return_to_path_max_size and valid_return_to_path?) to validate redirect targets.
