CVE-2026-82467

Name	CVE-2026-82467
Description	Rodauth before 2.47.0 fails to validate protocol-relative return-to paths in confirm_password, login_return_to_requested_location, and two_factor_auth_return_to_requested_location features. Attackers can craft paths with leading double slashes that browsers resolve as protocol-relative URLs, redirecting authenticated users to attacker-controlled sites after login or password confirmation.
