This pull request introduces comprehensive enterprise-grade security enhancements to AgentFlow CLI, including new authentication and authorization systems, production safety checks, improved error and log sanitization, and secure middleware for HTTP requests. It also updates documentation to guide users in configuring these features for production deployments.

Security and Authorization Enhancements:

  • Added a pluggable authorization backend system with an abstract AuthorizationBackend interface and a default permissive implementation, allowing custom resource-level access control logic.
  • Introduced a unified FastAPI dependency (RequirePermission) for combining authentication and authorization checks in endpoints, simplifying secure API development.
  • Updated configuration to support custom authentication and authorization backends via agentflow.json and added a property for authorization backend path in GraphConfig. [1] [2]

Production Security and Middleware:

  • Enforced production security best practices in Settings, including request size limits, security headers (HSTS, XSS, CSP, etc.), and startup warnings for insecure configurations (e.g., wildcard CORS, debug mode, open API docs). [1] [2]
  • Added middleware for request size limiting (RequestSizeLimitMiddleware) and security headers (SecurityHeadersMiddleware) to mitigate DoS attacks and enforce secure HTTP headers. [1] [2]

Error and Log Sanitization:

  • Implemented error message sanitization for production, ensuring that detailed internal errors are not exposed to end users.
  • Integrated a sanitizing log formatter to automatically redact sensitive information from logs. [1] [2]

Documentation and Guidance:

  • Expanded the README.md with a detailed security section, including feature overview, production checklist, configuration examples, and references to a comprehensive security guide.

Other Improvements:

  • Updated dependencies and imports for new security features and validation utilities.
  • Removed outdated or redundant content from Task.md.

These changes collectively provide a robust foundation for secure, production-ready deployments of AgentFlow CLI.

…headers, rate limiting, and SSL/TLS settings

feat(auth): Implement Role-Based Access Control (RBAC) authorization backend with multiple role support

test(security): Add unit tests for error message sanitization and error handling in production and development modes

test(security): Add unit tests for request size limit middleware and ensure proper error responses

test(security): Add unit tests for security configuration warnings and ensure proper logging in production

test(security): Add unit tests for security headers middleware, ensuring all headers are added correctly and configurations work

chore(deps): Update agentflow-cli version to 0.2.6 in dependency lock file
- Remove obsolete Task.md file.
- Implement load_and_bind_auth and load_and_bind_authorization functions in loader.py for better auth handling.
- Update authorization.py to remove unused pass statement.
- Modify permissions.py to use collections.abc for Callable type.
- Clean up settings.py to improve warning messages and logging.
- Refactor setup_middleware.py to streamline middleware imports.
- Add noqa comments to handle linter warnings in handle_errors.py and security_headers.py.
- Improve log_sanitizer.py to enhance data sanitization logic.
- Delete unused test.py file.
- Create a new plan.md for the development playground feature, outlining goals, implementation options, and acceptance criteria.
