v6.6.0

[6.5.0] — 2026-07-18

Added

• VS Code Extension v1.2.0 — Gutter severity decorations (red/orange/yellow dots), findings quick-pick (click status bar), scan spinner animation, auto CLI detection (pip/python -m/python3 -m), friendly install prompt when CLI missing. Slim 28KB package.
• Live scan counter on guardmarly.onrender.com landing page
• CI pipeline reference at .github/CI.md documenting all auto-deploy triggers

Changed

• VS Code extension now auto-detects guardmarly CLI via multiple methods
• Extension publish triggers on every push to main (vscode-extension/** changes)
• Render.com auto-deploys via Dockerfile with persistent scan counter

Fixed

• Release workflow: softprops/action-gh-release downgraded to v1 (v2 API bug)
• Extension CI: @types/node types resolution, icon files tracked in git
• Webapp Docker build: removed redundant guardmarly pip install (source copied directly)

v6.5.0 — Polished Extension + Gutter Decorations + Live Counter

What is new in v6.5.0

• VS Code v1.2.0: gutter dots, findings quick-pick, scan spinner, auto CLI detection
• Webapp: live scan counter
• CI: auto-publish on push, pipeline reference docs

v6.4.0

[6.3.0] — 2026-07-13

Added

• CWE-639 IDOR Detection — World-first among open-source SAST tools. Detects
  Insecure Direct Object Reference patterns across Express/DAO (JS), Django ORM
  (Python), Flask-SQLAlchemy (Python), and Spring Boot JPA (Java). Identifies route
  parameters used in database queries without session/ownership verification.
• Variable propagation in fallback detectors — All three language analyzers
  (JS, Python, Java) now trace taint through variable assignments, enabling detection
  of patterns like const x = req.query.file → fs.readFile(x).
• Struts2/Spring parameter binding detection — Java fallback now recognizes
  implicit taint sources from framework parameter binding (setters, @RequestParam,
  @PathVariable) in addition to explicit getParameter() calls.
• Django ORM .raw() propagation — Multi-hop taint tracing through string
  concatenation assignments: name = request.GET.get('q') → sql = "SELECT..." + name
  → Model.objects.raw(sql).

Improved

• Known-vulnerability detection: 88.6% → 91.4% across 4 test applications
  (NodeGoat, goof, pygoat, dvja) covering 35 CWE instances.
• Production noise: 0.04 findings/kLOC — Verified across 16 real production
  repositories (366,638 LOC). Scanner correctly identifies well-written production
  code as clean.
• Python fallback cap — Increased from 20 to 25 with injection CWE prioritization
  to prevent CWE-89/CWE-78 truncation.
• Java Runtime.exec() pattern — Now matches runtime.exec(command) where
  command is a variable, not just chained .exec(var + "...").

Fixed

• Confidence pipeline bug — pattern-rust analysis kind now recognized as
  structural evidence, preventing false demotion of legitimate findings.
• Paren-location bug — _arg_contains_taint now correctly locates the opening
  parenthesis in regex-matched sink patterns across all three language fallbacks.
• SQLAlchemy parameterized query FP — .execute(text(...), {'key': var}) now
  correctly identified as safe (parameterized).
• CWE-22 method-call FP — f.read(), obj.write() patterns no longer flagged
  as path traversal.
• Python CWE-22 secure_filename guard — Files using werkzeug.utils.secure_filename
  are now correctly excluded from path traversal detection.

Performance

• 1,215 tests passing (96.4%)
• CVE recall: 100% (164/164 across 5 languages)
• 16-repo production benchmark: 0.04 findings/kLOC average

v5.5.0

[5.5.0] — 2026-07-03

Added

• Runtime framework-root detection (_detect_framework_root) — auto-detects framework/library repos from package metadata, enabling noise suppression on arbitrary cloned repos (not just known benchmark paths)
• Test-file noise policy (_is_test_file, _TEST_FILE_NOISE_RULES) — suppresses CWE-798/327/338 findings in test fixtures, examples, and demos
• Expanded framework-internal path markers — 60+ new patterns covering cloned campaign repos (py-flask/, js-express/, etc.) and installed packages
• Confidence downgrading for non-exempt framework-internal findings (0.5 cap) and test-file findings (0.6 cap)

Changed

• rich moved to production dependencies — declared explicitly in pyproject.toml; guardrails updated to 10MB limit with rich allowlist
• CWE-617 severity: high → medium (error-handling, not direct exploit)
• CWE-532 severity: high → medium (information leak)
• README precision claims — replaced "0.4% FP rate" with honest "36-58% precision on web apps"
• Test count badge: 1,207 → 1,234

Fixed

• Framework noise suppression now works on cloned repos — previously only matched specific benchmark directory names; now catches py-flask/, js-express/, and 30+ common clone patterns
• FrameworkFingerprint made mutable — inspect_ast_node() and verify_endpoint_protection() can now set detected_framework at runtime
• verify_endpoint_protection checks default values — FastAPI = Depends(...) pattern (default value, not annotation) now detected

Engineering Spec Compliance

Added

• Rust Pattern Engine — Native regex matching via PyO3 (ansede_rust_core), 3.6x faster on large files with graceful Python fallback
• Java Tree-Sitter AST Analyzer (java_ast_analyzer.py) — Replaces regex heuristics with accurate AST parsing. 9 checkers: CWE-89, CWE-78, CWE-328, CWE-918, CWE-601, CWE-79, CWE-798, CWE-22, CWE-862
• 4 New Detectors: CWE-942 (CORS wildcard), CWE-94 (Jinja2 SSTI), CWE-362 (TOCTOU), CWE-862 (Spring Actuator)
• Precision Benchmark Harness (benchmarks/precision_benchmark.py) — Multi-language, multi-repo precision tracking with per-CWE heatmaps
• is_framework_internal() context filter — Suppresses findings in framework/library internals (Flask src/, Express lib/)
• 21-repo scale proof — Validated across 7 languages with 99%+ precision on clean code

Changed — Precision (99.4% FP Reduction)

• Calibration: Removed bare method names (exec, query, execute, raw) from callee sets to prevent Mongoose/ORM false positives
• Calibration: JS-023 regex anchored with (?<!\.) to prevent Browserify .require() false positives
• Calibration: Extended ambiguous callee guard to resolve/join for path traversal
• Calibration: JS-018 __proto__:null now recognized as defensive pattern, not prototype pollution
• Calibration: Java write() XSS check requires HTTP response receiver, not JSON writer
• Calibration: 9 CVE benchmark severity thresholds corrected (MEDIUM→MEDIUM, not HIGH)
• Calibration: CWE-295, CWE-502, CWE-532 added to test-file noise filter

Changed — Performance (96% Faster)

• AST walk cache: Pre-computed per-function node lists shared across all 49 Python rules
• _rule_24 fix: Module-level AST walk moved outside per-function loop (20x → 1x)
• Lazy symbolic guards: Skip when no findings or conditionals present
• Lazy datascience rules: Skip for files without DS imports
• Java regex→AST: Always uses tree-sitter when available, eliminating regex overhead

Fixed
