CVE-2026-44170: MariaDB: Argument injection in CONNECT REST Xcurl on Windows via unsanitized URL

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.

Security readout for executives and security teams

Plain-English summary

A database user could turn a MariaDB CONNECT REST table URL setting into shell command execution on a Windows database server. This is critical because operating-system execution on a database host can expose data, alter systems, or disrupt service. The provided sources do not show confirmed active exploitation.

Executive priority

Treat this as urgent for Windows MariaDB environments using CONNECT REST. It enables command execution on the database server by an authenticated user, so affected systems should be upgraded or tightly restricted quickly, especially where many users or applications can define database tables.

Technical view

MariaDB Server on Windows interpolated the CONNECT engine REST HTTP table attribute into a curl command line without proper sanitization. This is CWE-78 OS command injection with CVSS 9.9. Affected versions are 10.6.1-10.6.25, 10.11.1-10.11.16, 11.4.1-11.4.10, 11.8.1-11.8.6, and 12.3.1.

Likely exposure

Exposure appears limited to MariaDB on Windows where an affected version has the CONNECT engine installed and REST support enabled. Practical risk depends on whether lower-privileged or untrusted database users can create or influence CONNECT REST table definitions or their HTTP attributes.

Exploitation context

The CVSS vector indicates network reachability, low attack complexity, low privileges required, no user interaction, changed scope, and high impact to confidentiality, integrity, and availability. KEV is false, and the source bundle does not provide evidence of exploitation in the wild.

Researcher notes

The advisory ties impact to unsanitized interpolation into curl command lines, not a generic MariaDB exposure. Keep analysis scoped to Windows, CONNECT installed, REST enabled, and affected version ranges. No public exploit status is established by the provided sources.

Mitigation direction

  • Upgrade MariaDB to 10.6.26, 10.11.17, 11.4.11, 11.8.7, or 12.3.2.
  • Prioritize Windows database servers with CONNECT engine and REST support enabled.
  • Restrict who can create or modify CONNECT REST tables until upgraded.
  • Review MariaDB and operating-system logs for suspicious CONNECT REST table activity.
  • Check MariaDB and OS vendor advisories for platform-specific package updates.

Validation and detection

  • Inventory MariaDB Server versions on Windows hosts.
  • Confirm whether CONNECT engine is installed and REST support is enabled.
  • Identify users or applications allowed to create or alter CONNECT REST tables.
  • Verify patched MariaDB versions after maintenance.
  • Review change records for recent CONNECT REST table HTTP attribute modifications.
