CVE-2026-44173: CWE-863: Incorrect Authorization 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 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.
AI Analysis
Technical Summary
MariaDB server contains an authorization bypass vulnerability in its handling of SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE SQL statements. Specifically, if the FROM clause consists solely of subqueries, the server does not verify whether the user has the FILE privilege before allowing these statements. This flaw affects multiple version ranges and a single version, allowing users with limited privileges to write files to the server filesystem without proper authorization. The issue has been fixed in versions 10.6.26, 10.11.17, 11.4.11, 11.8.7, and 12.3.2.
Potential Impact
An attacker with privileges to execute SELECT statements but without the FILE privilege could write files to the server filesystem by exploiting this vulnerability. This could lead to denial of service or other impacts related to unauthorized file creation. The CVSS v3.1 base score is 5.0 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impact limited to availability.
Mitigation Recommendations
A fix is available and has been released 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 vulnerability. Patch status is confirmed by the vendor advisory. No other mitigation steps are specified.
