## Technical details

The LogController fails to verify authorization before allowing authenticated users to call /log/add, /log/update, /log/delete, and /log/deleteBatch endpoints. An attacker can fabricate audit log entries with arbitrary user IDs and IP addresses, modify existing logs, or perform hard deletes to erase records. The vulnerability requires prior authentication but no additional privilege escalation.
