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 allowed SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE without verifying the FILE privilege if the FROM clause contained only subqueries. 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
CVE-2026-44173 is an incorrect authorization vulnerability in MariaDB server where certain SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE queries bypass FILE privilege checks if the FROM clause contains only subqueries. This affects multiple MariaDB versions: 10.6.1 through 10.6.25, 10.11.1 through 10.11.16, 11.4.1 through 11.4.10, 11.8.1 through 11.8.6, and version 12.3.1. The issue allows unauthorized file writing operations due to missing privilege verification. The vulnerability has been patched in MariaDB versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2. The CVSS v3.1 base score is 5.0 (medium severity) with network attack vector, low attack complexity, requiring low privileges, no user interaction, and partial impact on availability only. Red Hat advisories confirm the issue and provide updated packages to remediate it.
Potential Impact
The vulnerability allows an attacker with low privileges to perform SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE operations without having the FILE privilege, but only when the FROM clause contains subqueries. This could lead to unauthorized file writes on the server, potentially impacting availability. There is no direct impact on confidentiality or integrity according to the CVSS vector. No known exploits in the wild have been reported.
Mitigation Recommendations
Fixes for 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. Red Hat provides updated packages for affected distributions, and applying these updates is recommended. Patch status is confirmed by vendor advisories. No additional mitigations are specified.
