Security Report

1.5

Use Caution1.5Critical Risk

The server has several security concerns that affect the score. It validates API keys but sends them in plain text parameters, logs authentication errors, and uses broad exception handling with dangerous eval/exec operations. A hardcoded test password and overly broad network permissions also present risks for a finance server. Supply chain analysis found 5 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.
