Java code execution via Data Source class loading
Published Sep 9, 2026 · Updated Sep 9, 2026
Improper code-resource control in Apache Impala 2.7.0 through 4.5.1 allows remote authenticated users to execute arbitrary Java code. The Data Source table path accepts an attacker-uploaded JAR from remote storage and loads its external Data Source class without sufficient authorization. The user must hold privileges to upload the file and create the table; successful exploitation runs code in the Impala service context.

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.
- Affected versionversion=2.7.0 <=4.5.1
