{"id":"CVE-2026-85985","state":"PUBLISHED","title":"MariaDB: Unauthorized file access via CONNECT engine UDFs","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, the CONNECT engine plugin file-access UDFs json_file(), bson_file(), jfile_make(), bfile_make(), and jbin_file() are affected because each does not enforce FILE privilege or the secure_file_priv setting. A low-privileged attacker can trigger the issue by calling a CONNECT file-access UDF with a filesystem path, then invoke a CONNECT file-access UDF to access a filesystem path and read or write files that the database account is not authorized to access, subject to operating-system permissions. 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.","publishedAt":"2026-10-16T16:21:14.677Z","updatedAt":"2026-10-16T17:05:42.975Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["MariaDB server"],"affected":[{"vendor":"MariaDB","product":"server","versions":[{"version":">= 10.6.1, < 10.6.28","status":"affected"},{"version":">= 10.11.1, < 10.11.19","status":"affected"},{"version":">= 11.4.1, < 11.4.13","status":"affected"},{"version":">= 11.8.1, < 11.8.9","status":"affected"},{"version":">= 12.3.1, < 12.3.3","status":"affected"},{"version":">= 13.0.1, < 13.0.2","status":"affected"}]}],"references":["https://github.com/MariaDB/server/security/advisories/GHSA-2245-9hm3-wxf6","https://github.com/MariaDB/server/commit/4f66ca1b69daf1b7e6a562ca8e86d77a6a70abfe","https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","https://jira.mariadb.org/browse/MDEV-40323"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85985.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85985","state":"PUBLISHED","datePublished":"2026-10-16T16:21:14.677Z","dateUpdated":"2026-10-16T17:05:42.975Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-04T19:17:36.245Z"},"containers":{"cna":{"title":"MariaDB: Unauthorized file access via CONNECT engine UDFs","descriptions":[{"lang":"en","value":"MariaDB server is a community developed fork of MySQL server.
