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."}], "lastModified": "2026-10-20T15:32:39.523", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6A6667AA-6A82-49E2-894B-318569872468", "versionEndExcluding": "10.6.28", "versionStartIncluding": "10.6.1"}, {"criteria": "cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C18A44B6-CEEF-47D7-9D60-04E6EBAFC785", "versionEndExcluding": "10.11.19", "versionStartIncluding": "10.11.1"}, {"criteria": "cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "47070DA5-F754-4FE1-957A-375C39D9029E", "versionEndExcluding": "11.4.13", "versionStartIncluding": "11.4.1"}, {"criteria": "cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "39AD11EC-57BE-4D2B-9A7C-E667E23A6940", "versionEndExcluding": "11.8.9", "versionStartIncluding": "11.8.1"}, {"criteria": "cpe:2.3:a:mariadb:mariadb:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E6988F1C-2D11-431B-BBE4-3AA8483627C8", "versionEndExcluding": "12.3.3", "versionStartIncluding": "12.3.1"}, {"criteria": "cpe:2.3:a:mariadb:mariadb:13.0.1:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E46FBE57-06D5-489E-9ECE-333F5F9AFD06"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
