Automated description summarized from trusted sources.

CVE-2026-48163 is a command injection vulnerability affecting MariaDB server, a community-developed fork of MySQL. This flaw occurs during the State Snapshot Transfer (SST) process, specifically when the rsync SST method is employed. The vulnerability arises because the donor node, during SST, interpolates parameters sent by the joiner node into the command line without adequate validation. This improper handling of parameters could allow a malicious joiner to execute arbitrary shell commands on the donor side. Affected versions include MariaDB server from 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. The issue has been addressed in versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2.

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.
