CVE-2026-16428Network attack vector

Authenticated code execution via misconfigured XSLT engine

Published Sep 14, 2026 · Updated Sep 14, 2026

Code injection in IBM DataStage on Cloud Pak for Data 5.4.0.0 allows remote authenticated users to execute arbitrary code through XSLT. The XSLT transformation engine executes attacker-controlled stylesheet operations without restrictions that prevent code execution. IBM has not disclosed the affected endpoint or enabled XSLT feature, so the precise service-level execution boundary remains unspecified.
