In MariaDB server version through 11.8.5, when server audit plugin is enabled with server_audit_events variable configured with QUERY_DCL, QUERY_DDL, or QUERY_DML filtering, if an authenticated database user invokes a SQL statement prefixed with double-hyphen (—) or hash (#) style comments, the statement is not logged.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1844 advisory.

    Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer).  Supported     versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and  9.0.0-9.6.0. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server.  Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 6.5 (Availability     impacts).  CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). (CVE-2026-34303)

(CVE-2026-3494)

    During the SST the donor node is interpolating parameters that the joiner sent into the command line. Not     all parameters were properly validated which could allow a malicious joiner to execute arbitrary shell     commands on the donor side via the mariabackup SST method. (CVE-2026-44168)

    mbstream did not check for /../ in the path when unpacking the archive. A proper backup can never contain     such paths, but a specially crafted archive could have caused mbstream to create files outside of the     target-dir path. (CVE-2026-44171)

    An application that was taking non-validated user input, escaping it with mysql_real_escape_string() and     sending it to the database using text protocol and big5 character set was vulnerable to SQL injections,     even though mysql_real_escape_string() was supposed to prevent them. (CVE-2026-44172)

    MariaDB allowed SELECT ... INTO OUTFILE and SELECT ... INTO DUMPFILE without verifying the FILE privilege     if the FROM clause contained only subqueries. (CVE-2026-44173)
