CVE-2026-44170: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in MariaDB server
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, MariaDB on WIndows with installed CONNECT engine and enabled REST support interpolated table HTTP attribute into the curl command line without proper sanitizing. This allows the user to execute shell commands on the server. This issue has been patched in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.

Technical Summary
MariaDB server 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 on Windows with the CONNECT engine installed and REST support enabled improperly sanitize the HTTP attribute when interpolating it into a curl command line. This improper neutralization of special elements (CWE-78) leads to OS command injection, allowing an attacker to execute arbitrary shell commands on the server. The issue has been addressed in MariaDB versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. The CVSS 4.0 base score is 6.3 (medium severity), with network attack vector, low complexity, no privileges required, no user interaction, and partial impacts on confidentiality, integrity, and availability. Red Hat advisories confirm the availability of patched packages.
Potential Impact
An attacker can execute arbitrary shell commands on the affected MariaDB server running on Windows if the CONNECT engine is installed and REST support is enabled. This can lead to compromise of the server, including unauthorized access, data manipulation, or disruption of service. The vulnerability has a medium severity rating with a CVSS score of 6.3. There are no known exploits in the wild at this time.
Mitigation Recommendations
A fix is available and has been released in MariaDB versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. Users should upgrade to these or later versions to remediate the vulnerability. Refer to the Red Hat advisories for detailed update instructions and apply the security updates promptly. No additional mitigations are specified by the vendor advisory.
