## Overview

Dockhand before 1.0.36 contains an open redirect vulnerability in the OIDC initiation endpoint that allows unauthenticated remote attackers to redirect authenticated users to attacker-controlled sites by injecting an unvalidated redirect query parameter. Attackers can craft a malicious link targeting the OIDC callback flow to capture authorization codes via the Referer header and conduct follow-up credential phishing against any Dockhand account after a legitimate login.
