Technical analysis, exploit verification, and patch instructions for CVE-2026-32710 impacting mariadb mariadb. Evaluated with CVSS Base Score of 8.5 (HIGH).

Original NVD Description

Source: NIST NVD
MariaDB server is a community developed fork of MySQL server. An authenticated user can crash MariaDB versions 11.4 before 11.4.10 and 11.8 before 11.8.6 via a bug in JSON_SCHEMA_VALID() function. Under certain conditions it might be possible to turn the crash into a remote code execution. These conditions require tight control over memory layout which is generally only attainable in a lab environment. This issue is fixed in MariaDB 11.4.10, MariaDB 11.8.6, and MariaDB 12.2.2.
