## Technical details

A blind SQL injection vulnerability exists in unauthenticated API routes (/user_panel_dashboard/ and /valid_token/) where the 'user' parameter is directly interpolated into a SQL query against the oauth_clients table. The route connects to MySQL as root, allowing attackers to perform time-based blind SQL injection to extract arbitrary database contents. Authentication is not required and the attack leverages local network access to the loopback interface.
