## Notable Items

### MariaDB Cluster (Galera)

* A parameter-injection gap existed in `wsrep_sst_rsync` because it failed to validate the joiner-supplied `WSREP_SST_OPT_REMOTE_USER` and `WSREP_SST_OPT_REMOTE_PSWD` values before interpolating them into the donor-written `stunnel.conf` and the `rsync` magic file [MDEV-39648](https://jira.mariadb.org/browse/MDEV-39648)
* An appropriately privileged user (with `SUPER` privileges) could execute shell commands as the `uid` of the `mariadbd` process because the values of the system variables `wsrep_sst_donor` and `wsrep_sst_receive_address`, which can be modified at runtime, were not properly sanitized when used to construct a shell command [MDEV-39676](https://jira.mariadb.org/browse/MDEV-39676)
* The `wsrep_notify_cmd` functionality was susceptible to a parameter-injection vulnerability, as it failed to validate the peer-supplied `wsrep_node_name` and `wsrep_node_incoming_address` values before interpolating them into the notification command line[ ](https://mariadb.com/docs/galera-cluster/)[MDEV-39721](https://jira.mariadb.org/browse/MDEV-39721)
* [Galera](https://mariadb.com/docs/galera-cluster/) updated to 26.4.27
