CVE-2026-48165 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, 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.
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. High-privileged users could exploit this vulnerability by manipulating the 'wsrep_sst_receive_address' or 'wsrep_sst_donor' global system variables to execute shell commands as the user ID of the 'mariadbd' process on the Galera joiner node. This exploitation is possible because the values of these system variables, which can be changed at runtime, were not properly sanitized before being used to construct a shell command.
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.
