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 exactly 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 leads to an OS command injection vulnerability (CWE-78), allowing remote attackers to execute arbitrary shell commands on the affected server. The issue has been addressed in subsequent patched versions.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary shell commands on the MariaDB server running on Windows, potentially leading to full system compromise. The vulnerability affects only configurations with the CONNECT engine installed and REST support enabled. The CVSS 4.0 base score is 6.3 (medium severity), reflecting network attack vector, low complexity, no privileges required, no user interaction, and limited confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Patches fixing this vulnerability are available in MariaDB server 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 issue. No vendor advisory content was provided to indicate alternative mitigations or that no action is required. Therefore, upgrading to a fixed version is the recommended remediation.
