CVE-2026-44168 Details
Description
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.
A vulnerability in MariaDB Server has been identified, allowing a malicious joiner node to execute arbitrary shell commands on the donor node during the State Snapshot Transfer (SST) process. This issue affects MariaDB versions 10.6.1 prior to 10.6.26, 10.11.1 prior to 10.11.17, 11.4.1 prior to 11.4.11, 11.8.1 prior to 11.8.7, and 12.3.1. The vulnerability arises because the donor node's 'wsrep_sst_mariabackup' method improperly validates parameters sent by the joiner, allowing for the injection of unsafe data that could be exploited to execute commands on the server.
Users can upgrade to MariaDB versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, or 12.3.2 to address this vulnerability.
