CVE-2026-48163 Details
Description
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.
A vulnerability exists in MariaDB server versions 10.6.1 prior to 10.6.27, 10.11.1 prior to 10.11.18, 11.4.1 prior to 11.4.12, 11.8.1 prior to 11.8.8, and 12.3.1. During the State Snapshot Transfer (SST) process, the donor node improperly validated parameters sent by the joiner, particularly those related to the rsync SST method. This lack of validation could enable a malicious joiner to execute arbitrary shell commands on the donor side.
Users can upgrade to MariaDB versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, or 12.3.2 to address this vulnerability. Alternatively, the vulnerable 'wsrep_sst_rsync' script can be removed from the donor host to prevent the rsync SST method from being used.
