Security Issue: Hardcoded PostgreSQL Database Credentials

File: characterization/tests.py

PostgreSQL database credentials are hardcoded:

conn = psycopg2.connect(dbname='postgres', port=5432, user='gabriel', password='qwerasdf', host='192.168.184.102')

Impact

• Database credentials exposed to anyone with repository access
• Internal network IP (192.168.184.102) exposed, aiding network reconnaissance
• If the database port is exposed, it could be accessed remotely

Recommendation

1. Remove hardcoded credentials from test files
2. Use environment variables or a test-specific config file
3. Never hardcode real database passwords in source code
