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 used in CONNECT engine tables. This attribute is directly interpolated into the curl command line without proper neutralization, enabling an attacker to execute arbitrary shell commands on the server. The vulnerability is classified as CWE-78 (Improper Neutralization of Special Elements used in an OS Command). The issue has been fixed in MariaDB versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. Red Hat advisories confirm the vulnerability affects only Windows installations with REST enabled and not Linux deployments. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and partial impacts on confidentiality, integrity, and availability.
Potential Impact
An attacker can exploit this vulnerability to execute arbitrary operating system commands on the affected MariaDB server running on Windows with the CONNECT engine and REST support enabled. This can lead to unauthorized code execution, potentially allowing the attacker to disable the database server, read or modify data without proper permissions, and hide malicious activities by executing commands as the database application user. The vulnerability impacts confidentiality, integrity, and availability of the system. Red Hat confirms that Linux deployments are not affected by this issue.
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 affected MariaDB server versions to these fixed versions or later. Red Hat has released updated packages for affected products and recommends applying these updates promptly. If upgrading is not immediately possible, disabling the CONNECT engine or REST support on Windows installations can mitigate the risk. No additional mitigations are specified by the vendor advisory.
