Summary
The armeria-saml library has an unvalidated redirect flaw: attacker-controlled RelayState values are reflected into the HTTP Location header after successful authentication, sending users to an attacker-chosen URL. An attacker can reach this remotely, but only with low-privilege access and with a user taking an action.
