CVE-2026-17443Network attack vector

Authenticated information disclosure via adapter-node XXE parsing

Published Sep 4, 2026 · Updated Sep 4, 2026

XXE injection in IBM App Connect Enterprise and Integration Bus for z/OS adapter nodes allows remote authenticated users to read sensitive data. The adapter-node XML path permits external entity references while the DataObject parser processes schema-modeled EIS messages; IBM has not disclosed the affected function. Reaching the flaw requires authenticated network access and an affected adapter-node flow in versions 12.0.1.0 through 12.0.12.28, 13.0.1.0 through 13.0.8.1, or 10.1.0.0 through 10.1.0.7; the reported consequence is sensitive-data disclosure.
