CVE-2026-16689

Credential disclosure via improper adapter-node logging

Published Sep 4, 2026 · Updated Sep 4, 2026

Credential exposure in affected IBM App Connect Enterprise and Integration Bus for z/OS releases allows local users to read logged credentials. Adapter nodes write credentials into logs rather than suppressing or redacting them, leaving secrets available to local log readers. Local access is required; affected releases are App Connect Enterprise 12.0.1.0 through 12.0.12.28 and 13.0.1.0 through 13.0.8.1, plus Integration Bus for z/OS 10.1.0.0 through 10.1.0.7, and IBM discloses no narrower adapter type or trigger.
