  - 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. (CVE-2026-44168)

  - MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, an application
    that was taking non-validated user input, escaping it with mysql_real_escape_string() and sending it to
    the database using text protocol and big5 character set was vulnerable to SQL injections, even though
    mysql_real_escape_string() was supposed to prevent them. This issue has been patched in versions 3.3.19
    and 3.4.9. (CVE-2026-44172)

  - MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.27,
    10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, 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 rsync SST method. This issue has been patched in versions 10.6.27, 10.11.18, 11.4.12,
    11.8.8, and 12.3.2. (CVE-2026-48163)

  - MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.27,
    10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1, a high-
    privileged MariaDB user could've used wsrep_sst_receive_address or wsrep_sst_donor global system variables
    to execute shell commands as the uid of the mariadbd process on the galera joiner node. This issue has
    been patched in versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. (CVE-2026-48165)

  - MariaDB server is a community developed fork of MySQL server. Versions 10.6.1 through 10.6.26, 10.11.1
    through 10.11.17, 11.4.1 through 11.4.11, 11.8.1 through 11.8.7, and 12.3.1 with `wsrep_notify_cmd`
    enabled would execute shell commands embedded in the name of the joiner node. This is fixed in 10.6.27,
    10.11.18, 11.4.12, 11.8.8, and 12.3.2. As a workaround, anyone who cannot upgrade now should disable
    `wsrep_notify_cmd`. (CVE-2026-49261)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
