From 4944d9327051348637e89c10e92f035a574ab996 Mon Sep 17 00:00:00 2001 From: shivasurya Date: Fri, 21 Nov 2025 18:48:43 -0500 Subject: [PATCH 1/2] Add enhanced SARIF formatter with code flows and metadata MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Rich rule metadata with help markdown and CWE references - Code flows for taint path visualization (source → sink) - Related locations for taint sources - Security severity scores for GitHub integration - Rule properties including tags and precision - Builder pattern API matching go-sarif library - Comprehensive tests achieving 97.5% coverage Features: - SARIF 2.1.0 compliance - Deduplicates rules across multiple detections - Supports both taint-local and taint-global detection types - Pattern matches do not include code flows (as expected) - Fallback from RelPath to FilePath for artifact locations Part of output standardization feature (PR #5). 🤖 Generated with [Claude

495743f912464c06c23ba474c1c9c93c092f5998 Mon Sep 17 00:00:00 2001 From: shivasurya Date: Fri, 21 Nov 2025 18:52:33 -0500 Subject: [PATCH 2/2] Integrate SARIF formatter in ci command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replaced old generateSARIFOutput() with output.SARIFFormatter - Uses enriched detections for rich SARIF output with code flows - Removed unused imports (sarif, json, encoding/json) - Skipped obsolete SARIF tests (replaced by output/sarif_formatter_test.go) - Cleaned up unused helper functions in tests Benefits over old implementation: - Code flows for taint path visualization - Related locations for taint sources - Help text with markdown formatting - Security severity scores for GitHub - Rule properties (tags, precision) - Consistent with JSON and CSV formatter pattern All tests passing, linting clean.
