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."], "name": "CVE-2026-86047", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "mariadb10.11", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "mariadb11.8", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Affected", "package_name": "mariadb", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "mariadb:10.11/mariadb", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "mariadb:10.3/mariadb", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "mariadb-devel:10.3/mariadb", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "mariadb", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "mariadb:10.11/mariadb", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "mariadb:11.8/mariadb", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/a:redhat:hummingbird:1", "fix_state": "Affected", "package_name": "mariadb10.11", "product_name": "Red Hat Hardened Images"}, {"cpe": "cpe:/a:redhat:hummingbird:1", "fix_state": "Affected", "package_name": "mariadb11.8", "product_name": "Red Hat Hardened Images"}, {"cpe": "cpe:/a:redhat:openstack:13", "fix_state": "Affected", "package_name": "mariadb", "product_name": "Red Hat OpenStack Platform 13 (Queens)"}], "public_date": "2026-10-16T16:37:04Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-86047\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-86047\nhttps://github.com/MariaDB/server/commit/2b28d1c424104429eeed43115ee6d8a803671d52\nhttps://github.com/MariaDB/server/commit/3646569225758c8225e7342783d775ef7c7570e5\nhttps://github.com/MariaDB/server/commit/5acb43522863c9bd6b91f354104ea247bf513e9a\nhttps://github.com/MariaDB/server/commit/9d4ffe23b25808f7858b2dc48106fbd60cf0e513\nhttps://github.com/MariaDB/server/commit/d5d741a3076f911b468518d6b06a917593498c5b\nhttps://github.com/MariaDB/server/releases/tag/mariadb-10.11.19\nhttps://github.com/MariaDB/server/releases/tag/mariadb-10.6.28\nhttps://github.com/MariaDB/server/releases/tag/mariadb-11.4.13\nhttps://github.com/MariaDB/server/releases/tag/mariadb-11.8.9\nhttps://github.com/MariaDB/server/releases/tag/mariadb-12.3.3\nhttps://github.com/MariaDB/server/releases/tag/mariadb-13.0.2\nhttps://github.com/MariaDB/server/security/advisories/GHSA-wxr3-wm3p-7w6p\nhttps://jira.mariadb.org/browse/MDEV-39776\nhttps://jira.mariadb.org/browse/MDEV-39818\nhttps://jira.mariadb.org/browse/MDEV-40308\nhttps://jira.mariadb.org/browse/MDEV-40311\nhttps://jira.mariadb.org/browse/MDEV-40312"], "threat_severity": "Important"}
