CVE-2026-12947

Local sensitive-data disclosure via Discovery Connector logging

Published Jul 30, 2026 · Updated Jul 30, 2026

Log disclosure in IBM App Connect Enterprise 12.0.1.0 through 12.0.12.27 and 13.0.1.0 through 13.0.7.2 allows local users to read sensitive data. Discovery Connector nodes write potentially sensitive information into log files, but IBM does not identify the logged fields or triggering operation. Access requires local permission to read the generated logs, and the reported consequence is read-only disclosure without integrity or availability impact.
