CVE-2026-47847Network attack vector

Replication metadata disclosure via hardcoded health-check credentials

Published Jun 18, 2026 · Updated Jun 18, 2026

Hard-coded credentials in Bitnami MariaDB Galera allow remote attackers to read replication metadata through the exposed database service. Initialization assigns the Galera replication health-check account the public monitor password and grants REPLICATION CLIENT access from any host. Network access to TCP port 3306 is required; authentication exposes primary host, port, binary-log file, and log position without write access or service interruption.
