Arbitrary file read via unfiltered JDBC parameters
Published Jul 15, 2024 · Updated Mar 14, 2025
Improper input validation in Apache Linkis DataSource 1.4.0 allows remote authenticated users to read arbitrary files via MySQL JDBC parameters. The DataSource Manager accepts attacker-controlled MySQL JDBC URL parameters without an effective denylist and passes them to the connector, enabling server-side file reads. Exploitation requires an authorized Linkis account and an enabled data-source service; the reported consequence is disclosure of files readable by the service account.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
