Doc Text:	A flaw was found in MariaDB, which can lead to SQL injection and privilege escalation. The SHOW CREATE SERVER and SHOW CREATE USER commands, as well as the mariadb-dump utility, do not properly quote identifiers and values when serializing SQL data. An authenticated, low-privileged attacker can exploit this issue by creating database objects with crafted identifiers or values to embed malicious commands into the generated SQL output. When the exported dump or output is subsequently executed, the injected SQL statements run with the privileges of the user applying the data.	Story Points:	---

Description OSIDB Bzimport 2026-10-16 16:52:31 UTC

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, SHOW CREATE SERVER, SHOW CREATE USER, and mariadb-dump are affected because each does not consistently quote identifiers and values when serializing SQL. A low-privileged attacker can trigger the issue when an attacker-created object with crafted identifiers or values is included in SHOW output or a dump, then create an object with crafted identifiers or values so generated SQL contains injected statements and execute attacker-injected SQL when the poisoned output is applied. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
