FKIE_CVE-2026-86047

Vulnerability from fkie_nvd - Published: 2026-10-16 17:17 - Updated: 2026-10-16 18:09
Severity
7.7 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:H/A:H
Summary
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.
