CVE-2020-4446Network attack vector

Authenticated performance-metrics disclosure via missing authorization

Published May 6, 2020 · Updated Sep 16, 2024

Incorrect authorization in IBM BPM 8.0, 8.5, and 8.6 and Business Automation Workflow 18.0 and 19.0 lets remote authenticated users read metrics. The performance-metrics display returns monitoring data without enforcing expected authorization checks. A low-privileged account and network access are required, and the documented impact is limited to metric confidentiality.
