Until official patches or updated Helm charts are applied, users should avoid deploying affected versions or manually change the replication user credentials if possible.

Description

Bitnami MariaDB Galera container images and Helm chart versions prior to specified releases contain a hardcoded default credential vulnerability. The Galera replication health-check user uses default credentials (monitor/monitor) with REPLICATION CLIENT privileges accessible from any host. The Helm chart did not allow configuring these credentials, causing deployments to use this publicly known credential by default. This vulnerability affects container images 10.6.x before 10.6.27-photon-5-r0, 10.11.x before 10.11.17-photon-5-r1, 11.4.x before 11.4.12-photon-5-r0, 11.8.x before 11.8.7-photon-5-r1, 12.3.x before 12.3.2-photon-5-r0 / 12.3.2-debian-12-r0, and Helm chart versions prior to 18.3.0.
