MariaDB server is a community developed fork of MySQL server. In versions 3.3.18 and 3.4.8, 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. This issue has been patched in versions 3.3.19 and 3.4.9.

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)

    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. (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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1845 advisory.
