CVE-2026-3494: CWE-778 (Insufficient Logging) in MariaDB Foundation MariaDB Server
CVE-2026-3494 is a medium severity vulnerability in MariaDB Server versions through 11. 8. 5 related to insufficient logging. When the server audit plugin is enabled with specific event filters (QUERY_DCL, QUERY_DDL, or QUERY_DML), SQL statements prefixed with double-hyphen (--) or hash (#) style comments by authenticated users are not logged. This can lead to incomplete audit trails for certain database activities. There is no information about an available patch or vendor advisory specifying remediation. No known exploits are reported in the wild.
AI Analysis
Technical Summary
This vulnerability in MariaDB Server affects versions up to 11.8.5 when the server audit plugin is enabled and configured to filter certain query events. Authenticated users executing SQL statements with comment prefixes (double-hyphen or hash) can bypass logging, resulting in insufficient audit records. This is classified under CWE-778 (Insufficient Logging). The CVSS 3.1 base score is 4.3, indicating medium severity with network attack vector, low attack complexity, and requiring privileges. No patch or official fix information is provided.
Potential Impact
The impact is limited to incomplete logging of certain SQL statements when specific audit plugin filters are active. This may hinder forensic investigations or audit compliance by missing some user actions. There is no direct impact on confidentiality or availability, but integrity impact is rated low due to potential undetected unauthorized changes.
Mitigation Recommendations
Patch status is not yet confirmed — check the MariaDB Foundation vendor advisory for current remediation guidance. Until a fix is available, administrators should be aware of the logging gap when using the server audit plugin with QUERY_DCL, QUERY_DDL, or QUERY_DML filters and consider alternative auditing configurations or additional monitoring to compensate for incomplete logs.
