The MARIADB_REPLICATION_USER and MARIADB_REPLICATION_PASSWORD environment variables defaulted to monitor and monitor respectively. This user is granted REPLICATION CLIENT privileges from any host ('%'). The Bitnami Helm chart for MariaDB Galera did not expose parameters to configure this user's credentials, resulting in all chart deployments using this publicly known credential by default.\n\nAffected versions — Container image: 10.6.x prior to 10.6.27-photon-5-r0; 10.11.x prior to 10.11.17-photon-5-r1; 11.4.x prior to 11.4.12-photon-5-r0; 11.8.x prior to 11.8.7-photon-5-r1; 12.3.x prior to 12.3.2-photon-5-r0 / 12.3.2-debian-12-r0.
