CVE-2026-44169Network attack vector

Routine-definition disclosure via role-derived EXECUTE access

Published Jun 12, 2026 · Updated Jun 12, 2026

Incorrect authorization in affected MariaDB Server releases allows remote authenticated users to read stored routine definitions. After a user activates a role with EXECUTE access, SHOW CREATE PROCEDURE returns the routine body without enforcing SHOW CREATE ROUTINE. Exploitation requires database access and a role granted EXECUTE on the target routine; it discloses routine source but does not alter data or service availability.
