CVE-2026-53989
Dockhand < 1.0.36 Open Redirect via OIDC Initiation Endpoint
Description
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.
