CVE-2026-47847
Bitnami MariaDB Galera container images and Helm chart are affected by a hardcoded default credential vulnerability in the Galera replication health-check user. 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. Affected 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. Helm chart: prior to 18.3.0.
