| CVE-2026-49261 | CRITICAL | 10.0 | Jun 11, 2026 | 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-2026-48165 | HIGH | 8.0 | Jun 12, 2026 | 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-2026-48163 | HIGH | 8.0 | Jun 12, 2026 | 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. |
| CVE-2026-44168 | HIGH | 8.0 | Jun 12, 2026 | MariaDB server is a community developed fork of MySQL server.

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 |
| CVE-2026-44171 | MEDIUM | 6.3 | Jun 12, 2026 | 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, mbstream did not check for /../ in the path when unpacking the archive. A proper backup can never contain such paths, but a specially crafted archive could have caused mbstream to create files outside of the target-dir path. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12 |
| CVE-2026-44170 | MEDIUM | 6.3 | Jun 12, 2026 | MariaDB server is a community developed fork of MySQL server.

INTO DUMPFILE without verifying the FILE privilege if the FROM clause contained only subqueries. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. |
| CVE-2026-44169 | MEDIUM | 4.3 | Jun 12, 2026 | MariaDB server is a community developed fork of MySQL server. From versions 11.4.1 to before 11.4.11, 11.8.1 to before 11.8.7, and 12.3.1, a user getting EXECUTE access to a stored routine via a role, could see the routine definition even without SHOW CREATE ROUTINE privilege.
