MariaDB Connector/J does not enforce allowLocalInfile=false on server-initiated LOCAL INFILE requests
GitHub lists this reviewed advisory for org.mariadb.jdbc:mariadb-java-client, org.mariadb.jdbc:mariadb-java-client, org.mariadb.jdbc:mariadb-java-client, org.mariadb.jdbc:mariadb-java-client. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

## Summary MariaDB Connector/J does not enforce `allowLocalInfile=false` when processing server-initiated LOCAL INFILE requests (protocol packet type `0xfb`). However, exploitation is constrained: the server can only request the exact filename the client already included in its `LOAD DATA LOCAL INFILE` query, it cannot redirect to arbitrary paths. ## Details When a client executes `LOAD DATA LOCAL INFILE '/path/to/file'`, the connector sends the filename to the server as part of the COM_QUERY. A rogue or MitM server responds with a `0xfb` packet echoing that same filename. The connector, without checking `allowLocalInfile`, transmits the file content. The bypass is therefore limited to the file the application itself intended to load. The attacker cannot escalate to other files (e.g. `/etc/passwd`) unless the application's own query targets them. The real-world risk is: - An application that uses `LOAD DATA LOCAL INFILE` on potentially sensitive files (credentials, exports, configs) and connects over an untrusted network. - `allowLocalInfile=false` is supposed to disable this entire mechanism as a defense-in-depth measure, but the flag is ignored. ## Impact

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
