Description Praise Ogwuche 2026-06-30 08:06:42 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.26, 10.11.1 to before 10.11.17, 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and 12.3.1, during the SST the donor node is interpolating parameters that the joiner sent into the command line. Not all parameters were properly validated which could allow a malicious joiner to execute arbitrary shell commands on the donor side via the mariabackup SST method. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.
