CVE-2026-85985

01/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.
