CVE-2026-81832Network attack vector

Authenticated data disclosure via external XML entities

Published Sep 4, 2026 · Updated Sep 4, 2026

XXE in the SAP Adapter in IBM App Connect Enterprise and Integration Bus for z/OS allows remote authenticated users to read sensitive data. The adapter's XML parser resolves attacker-controlled external entity references instead of restricting them to the intended XML content. A valid low-privilege account and a deployed SAP Adapter path are required, and the reported consequence is disclosure only.
