NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby-rodauth package and not the ruby-rodauth package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Rodauth before 2.47.0 contains a time-based one-time password reuse vulnerability in the otp feature that fails to track the last accepted code timestamp. Attackers who observe a valid TOTP code can replay it during the drift window to bypass the second authentication factor.
