CVE-2023-25601Network attack vector

Unauthenticated gateway access via missing connection token

Published Apr 20, 2023 · Updated Feb 13, 2025

Improper authentication in Apache DolphinScheduler 3.0.0 through 3.1.1 allows remote attackers to access the Python gateway via socket bytes. Affected builds construct the Py4J GatewayServer without setting an authentication token, so arbitrary socket clients are accepted as trusted. Exposure requires the optional Python gateway to be enabled; Apache documents it as disabled by default, and published sources do not further bound callable operations.
