Summary
A vulnerability in MariaDB on Windows with the CONNECT engine installed and REST support enabled allows interpolation of the table HTTP attribute into the curl command line without proper sanitization. This enables the user to execute shell commands on the server.
Risk Assessment
An attacker can remotely execute shell commands on the server, leading to full system compromise, data theft, or service disruption.
Recommendation
Immediately update MariaDB to version 10.6.26, 10.11.17, 11.4.11, 11.8.7, or 12.3.2. If updating is not possible, disable the CONNECT engine or REST support.

- CVE-2026-48163High
A vulnerability in MariaDB allows a malicious joiner node to execute arbitrary shell commands on the donor node during the SST (State Snapshot Transfer) process using the rsync method. The issue stems from insufficient validation of parameters sent by the joiner, which are interpolated into the command line on the donor side.
- CVE-2026-44173Medium
A vulnerability in MariaDB allows SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE without the required FILE privilege when the FROM clause contains only subqueries. Affected versions include 10.6.1 to 10.6.26, 10.11.1 to 10.11.17, 11.4.1 to 11.4.11, 11.8.1 to 11.8.7, and 12.3.1.
- CVE-2026-44168High
A vulnerability in MariaDB allows a malicious joiner node to execute arbitrary shell commands on the donor node during the SST (Snapshot State Transfer) process using the mariabackup method. The issue is caused by insufficient validation of parameters sent by the joiner, which are interpolated into the command line on the donor side.
- CVE-2026-3494Medium
In MariaDB server up to version 11.8.5, when the server audit plugin is enabled with the server_audit_events variable configured with QUERY_DCL, QUERY_DDL, or QUERY_DML filtering, an authenticated database user can invoke a SQL statement prefixed with double-hyphen (--) or hash (#) style comments, which is not logged.
