Short explanation
The CONNECT engine plugin file-access UDFs in MariaDB server do not enforce the FILE privilege or the secure_file_priv setting. A low-privileged attacker can call these UDFs to read or write files that the database account is not normally authorized to access.
This vulnerability allows low-privileged users to bypass database boundaries and perform unauthorized file read and write operations on the underlying file system.
What should be done?
- Update software versions or follow the vendor advisory
- Restrict the use of affected UDFs
- Review database account permissions
Chain of evidence and sources
CONNECT motoru UDF'leri FILE yetkisini veya secure_file_priv ayarını zorunlu kılmamaktadır.

Show the technical text from the sources
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.
