Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache DolphinScheduler's dolphinscheduler-api package, versions before 3.4.2, has a DataSource API that lacks an authorization check, so it can expose metadata for arbitrary data sources. The source does not say what kind of access an attacker needs, but the disclosure is of data source metadata. Upgrade to version 3.4.2, which fixes the issue.
