CVE-2025-4057

Cross-broker access via reused generated credentials

Published May 26, 2025 · Updated Nov 20, 2025

Weak credentials in Red Hat AMQ Broker Operator before 2.0.3 allow local users to access another broker through reused credentials. ProcessCredentials used process-wide defaults for AMQ_USER, AMQ_PASSWORD, AMQ_CLUSTER_USER, and AMQ_CLUSTER_PASSWORD instead of generating values per CR. Low-privileged access to one OpenShift CR secret is required, after which identical credentials expose data protected by a separate CR.
