July 2025 monthly summary highlighting business value and technical achievements across yaklang/yaklang and yaklang/yakit. Key focus areas were strengthening risk assessment pipelines, expanding configurability of codec flows, and broadening security coverage in Go. Key features delivered: - SSA Risk Difference Calculations and Cross-Scan Diffing: centralizes risk-diff logic, improves filtering by difference, and adds test coverage for added, removed, and unchanged risks. Includes runtime-id comparisons, GRPC riskdiff query filters, and a risk-diff database API. - Codec Flow Management via gRPC API: adds and streamlines endpoints for saving and updating codec flow configurations, introducing an initial FlowId-based design and subsequent FlowName-based updates/retrieval for simplicity. - Go Security Rules Expansion: expands vulnerability coverage with new SSTI, CSRF, XXE, and SQL injection rules and refactors type information handling in the Go analysis engine. - Codec Flow Configuration API Upgrade: introduces UpdateCodecFlow RPC to modify existing codec flows; removes unused FlowId from CustomizeCodecFlow to simplify protocol. - SSA OrType and Type System Improvements (bug): fixes retrieval of OrType information, correctly handling nested OrTypes and deduplicating types to ensure methods are accessible with union types. Major bugs fixed: - OrType retrieval and type-system robustness: clarified method access for union/OrType combinations and improved SSA option builder behavior with OrTypes. - Stability and test coverage enhancements across risk-diff and diff tests to reduce regressions in cross-scan comparisons. Overall impact and accomplishments: - Improved accuracy and reliability of risk-diff across scans, enabling faster and more precise remediation decisions. - Increased configurability and maintainability of codec flows, reducing time-to-market for new configurations and simplifying client integration. - Expanded security coverage in Go analysis, reducing exposure to SSTI, CSRF, XXE, and SQL injection vulnerabilities. - Broadened API ergonomics with FlowName-based operations and cleaner protocol by removing redundant FlowId fields. Technologies/skills demonstrated: - Go, gRPC, and API design; SSA analysis and type-system reasoning; test coverage and quality improvements; security rule expansion; and protocol simplification.
