Mar 1, 2025March 2025 summary for lowcoder (lowcoder-org/lowcoder): Delivered critical fixes and an enterprise-ready API enhancement that strengthen data integrity, security, and cross-organization data portability. Implemented a comprehensive fix for dynamic SQL ORDER BY replacement to ensure all occurrences are replaced and sort values are validated to prevent SQL injection, accompanied by two commits. Added a new API endpoint to fetch a library query object by ID to support Enterprise Edition import/export workflows, including service method, implementation, controller exposure, and endpoint definitions. These deliverables improve reliability of query execution, enable smoother enterprise data exchange, and demonstrate strong security-conscious coding and API design.

Feb 1, 2025February 2025: Security, reliability, and performance gains across lowcoder. Key deliverables include security hardening (CORS), improved data source authentication reliability, targeted enterprise routing fixes, enhanced Oracle data handling, and backend API efficiency improvements. Notable updates: CORS policy hardening in the Node.js service; Oracle BLOB handling in JSON/ResultSets with Base64 encoding; Oracle JDBC driver upgrade; Meta API performance and view-model enhancements; improved data source authentication behavior when using 'inherit from login'. Major bugs fixed include correct organization routing in enterprise mode, a null-pointer guard for editing DSL retrieval, and refined authentication handling. Overall impact: stronger security posture, more reliable cross-origin requests, more efficient data fetches with smaller payloads, and improved observability. Technologies demonstrated: Node.js with cors middleware, Oracle JDBC, JSON/Base64 encoding, batch meta APIs, and new view models; enhanced event auditing and headers (where applicable).
