Security Report

4.2
Use Caution4.2High Risk

Scherlok is a data quality monitoring tool with generally sound architecture and appropriate security practices. Authentication and authorization are properly delegated to database connectors, and credentials are stored via environment variables rather than hardcoded. However, there are moderate concerns around input validation on webhook URLs, SQL query construction patterns that could be vulnerable to injection, and subprocess execution in the dbt-run-and-watch command without full validation. Permissions are well-scoped to the tool's purpose (database read-only access, network for webhooks/alerts, file I/O for local store). Supply chain analysis found 10 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
