Greptile Summary

This PR strengthens security across authentication, authorization, and SQL injection prevention. The changes centralize authentication logic through a new checkHybridAuth helper, add comprehensive permission checks to API routes, and implement query validation for database operations.

Key improvements:

• Centralized authentication via checkHybridAuth supporting session, API tokens, and internal JWT
• Added authorization checks to jobs, execution logs, memory, and template endpoints using workflow/workspace permissions
• Implemented SQL/NoSQL injection prevention with query validation and identifier sanitization for MySQL, PostgreSQL, and MongoDB
• Updated CSP configuration to restrict localhost URLs to development environment only
• Created reusable permission helpers in lib/templates/permissions.ts for cleaner authorization code

Security concerns:

• MySQL and PostgreSQL WHERE clauses accept raw strings that are validated but not fully parameterized, creating potential injection vectors if user-controlled values are embedded in WHERE conditions (e.g., id = ${userInput}). While dangerous patterns are blocked, this is less secure than fully parameterized queries.

Confidence Score: 4/5

• This PR significantly improves security but has WHERE clause parameterization issues in SQL utilities that should be addressed
• Score reflects strong authentication/authorization improvements and comprehensive NoSQL injection prevention, but MySQL/PostgreSQL WHERE clause handling uses string concatenation instead of full parameterization, which is a security risk even with pattern validation
• Pay close attention to apps/sim/app/api/tools/mysql/utils.ts and apps/sim/app/api/tools/postgresql/utils.ts for WHERE clause parameterization issues
