{"id":"CVE-2026-86047","published":"2026-10-16T17:17:52.063","lastModified":"2026-10-16T18:09:12.750","description":"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.","cvssScore":7.7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:N/I:H/A:H","cwes":["CWE-89"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MariaDB/server/commit/2b28d1c424104429eeed43115ee6d8a803671d52","tags":[]},{"url":"https://github.com/MariaDB/server/commit/3646569225758c8225e7342783d775ef7c7570e5","tags":[]},{"url":"https://github.com/MariaDB/server/commit/5acb43522863c9bd6b91f354104ea247bf513e9a","tags":[]},{"url":"https://github.com/MariaDB/server/commit/9d4ffe23b25808f7858b2dc48106fbd60cf0e513","tags":[]},{"url":"https://github.com/MariaDB/server/commit/d5d741a3076f911b468518d6b06a917593498c5b","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":[]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-wxr3-wm3p-7w6p","tags":[]},{"url":"https://jira.mariadb.org/browse/MDEV-39776","tags":[]},{"url":"https://jira.mariadb.org/browse/MDEV-39818","tags":[]},{"url":"https://jira.mariadb.org/browse/MDEV-40308","tags":[]},{"url":"https://jira.mariadb.org/browse/MDEV-40311","tags":[]},{"url":"https://jira.mariadb.org/browse/MDEV-40312","tags":[]}],"exploitRefs":[{"url":"https://github.com/MariaDB/server/commit/2b28d1c424104429eeed43115ee6d8a803671d52","tags":[]},{"url":"https://github.com/MariaDB/server/commit/3646569225758c8225e7342783d775ef7c7570e5","tags":[]},{"url":"https://github.com/MariaDB/server/commit/5acb43522863c9bd6b91f354104ea247bf513e9a","tags":[]},{"url":"https://github.com/MariaDB/server/commit/9d4ffe23b25808f7858b2dc48106fbd60cf0e513","tags":[]},{"url":"https://github.com/MariaDB/server/commit/d5d741a3076f911b468518d6b06a917593498c5b","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","tags":[]},{"url":"https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","tags":[]},{"url":"https://github.com/MariaDB/server/security/advisories/GHSA-wxr3-wm3p-7w6p","tags":[]}],"hasPoc":true,"ai":null}
