CVE-2026-3494: MariaDB Server Audit Plugin Comment Handling Bypass
Noroxi assessment
Priority: Monitor (action score 21/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.30% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: azl3 mariadb 10.11.15-1 on Azure Linux 3.0 10.11.16-1; cbl2 mariadb 10.6.24-1 on CBL Mariner 2.0 10.6.25-1.
Low priority for now. Upgrade to azl3 mariadb 10.11.15-1 on Azure Linux 3.0 10.11.16-1; cbl2 mariadb 10.6.24-1 on CBL Mariner 2.0 10.6.25-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
