CVE-2026-97380: MariaDB GRANT PROXY authorization bypass with empty password

CVE-2026-97380 · Severity: high · CVSS 8.8 · Published 2026-10-16

MariaDB is a database server used by organizations to store and manage business data. A flaw in the GRANT PROXY statement allows a low-privileged attacker to reset passwords on other database accounts, potentially granting themselves elevated privileges and full access to sensitive data. An attacker needs the ability to interact with the database and know another account name to exploit this vulnerability.

Technical details

The GRANT PROXY statement incorrectly treats an empty password in an IDENTIFIED clause as if no authentication were specified, causing it to check the wrong set of grantor privileges. An attacker with database access can exploit this logic error to change passwords on arbitrary named accounts, bypassing the intended authorization checks. The fix distinguishes between "empty authentication specified" and "authentication not specified".
