+| **7.2.0** | 2026-04-29 | **Batch B release.** Closes the remaining critical-review B-tier scanner defects (B3, B5, B6, B7) and lands the v7.2.0 evasion-arsenal hardening patches (E1, E4, E5, E7, E15, E16, E17, E18). **Added:** B6 destructuring/spread taint propagation in `taint-tracer.mjs`; B7 token-overlap typosquat fallback in `string-utils.mjs`/`dep-auditor`/`supply-chain-recheck`; E15 `.claude/agents/*.md` glob in `memory-poisoning-scanner`; E1 PUA-A/PUA-B coverage in `containsUnicodeTags`; E16 `foldHomoglyphs` (Cyrillic/Greek → Latin via NFKC) before every pattern match in `scanForInjection` (with ASCII fast-path); E17 `LLM_SECURITY_ESCALATION_WINDOW` env-var + 20-call MEDIUM secondary advisory in `post-session-guard`; E4 markdown link-title scan, E5 SVG `<desc>/<title>/<metadata>/<foreignObject>` extractor, E7 generalized HTML comment scan in `post-mcp-verify`. **Changed:** B5 entropy two-stage pipeline — new `classifyFileContext` in `entropy-scanner.mjs` gates rules 11-13 (GLSL/CSS-in-JS/inline-markup line-proximity) on `context !== 'code-dominant'`, ending the v7.0.0 polyglot false-negative class while preserving existing behaviour for short single-line fixtures. E18 entropy rule 18 — `MARKDOWN_IMAGE_CDN_HOSTS` allowlist + secret-in-query pre-check; non-CDN hosts and CDN URLs carrying secret-shaped query tokens fall through to entropy classification. v1 → v2 risk-formula constants (BLOCK ≥65, WARNING ≥15) unified across `commands/scan.md`, `commands/audit.md`, `agents/mcp-scanner-agent.md`, `agents/posture-assessor-agent.md` with a `tests/lib/doc-consistency.test.mjs` drift-guard. **Documentation:** B3 `info` severity is scoring-inert — documented in `severity.mjs` JSDoc and CLAUDE.md. **Red team:** 8 new attack scenarios (UNI-007/008/009, MCP-005/006/007/008, TRI-004); attack-simulator 64 → 72, 100 % pass. **Tests:** 1522 → 1665+ (Wave 1-6 cumulative). |
 | **7.1.0** | 2026-04-29 | **Critical-review patch.** Closes the highest-impact items from the v7.0.0 adversarial review (`docs/critical-review-2026-04-20.md`, grade B-). Bug-fixes + documentation honesty-sweep, no new features. **Fixed:** (1) `pre-write-pathguard.mjs` regex hole — `.env.production.local.backup`, `.env.prod.local.bak`, etc. could be written. New regex `/[\\/]\.env(\.[A-Za-z0-9._-]+)*$/` covers arbitrary multi-segment suffixes; `.envrc` still allowed. (2) `post-session-guard.mjs` — `LLM_SECURITY_TRIFECTA_MODE=block` only blocked when trifecta was MCP-concentrated or hit a sensitive path; distributed trifectas across MCP servers were advisory-only. AND-gate removed. (3) `scanners/lib/severity.mjs` JSDoc + CHANGELOG arithmetic — `riskScore({critical: 4})` is 93, not 90 (computation always was). **Changed (honesty-sweep, critical-review §9):** "Trustworthy scoring" → "Severity-dominated risk scoring (v2 model)"; "Context-aware entropy scanner" → "Rule-based entropy scanner with file-extension skip, 8 line-level suppression rules, and configurable policy"; "1487 tests" → "1511 unit and integration tests; mutation-testing coverage not published"; "Fully Schrems II compatible" → "Schrems II compatible in default offline mode. Optional OSV.dev enrichment (`supply-chain-recheck --online`) transmits package identifiers to a Google-operated API and is a separate compliance consideration"; "Rule of Two enforcement" → "Rule of Two detection (configurable; default `warn`; blocks on high-confidence trifectas in opt-in `block` mode; distributed trifectas detected but not blocked by default)"; "Hardened ZIP extractor" → suffix " — no fuzz-testing results published to date"; "defense-in-depth" preserved but quantified in `docs/security-hardening-guide.md` §4: "three independent detection layers with documented bypass classes". **CaMeL claim toned down:** `post-session-guard.mjs:646` and `CLAUDE.md:184` now describe the implementation honestly — opportunistic byte-matching of truncated output fingerprints (first 200 bytes, SHA-256/16-hex tag); not semantic data-flow tracking; trivially bypassed by mutation, summarisation, or re-encoding. Inspired by CaMeL (DeepMind 2025) but not a CaMeL capability-tracking implementation. **Tests:** +24 (+8 pathguard multi-segment + 1 distributed-trifecta + 15 verdict/riskBand co-monotonicity sweep + 1 `riskScore({critical: 4}) === 93` anchor). 1511 tests (was 1487). All green. **Why:** the critical-review CISO perspective (§F) flagged overclaim language as a blocker for regulated environments — toning it down does not weaken the actual defenses; it lets users trust the documentation. |
 | **7.0.0** | 2026-04-19 | **Trustworthy scoring (BREAKING).** Three changes target the false-positive cascade on real codebases (scan of hyperframes.com gave `BLOCK / Extreme / 100` with ~70% noise). **1. Risk-score v2** (`scanners/lib/severity.mjs`) — severity-dominated, log-scaled within tier. Replaces sum-and-cap that collapsed every non-trivial scan to 100/Extreme. Tiers: critical → 70–95, high only → 40–65, medium only → 15–35, low only → 1–11. Verdict cutoffs realigned (BLOCK ≥65, WARNING ≥15) for band co-monotonicity. **2. Context-aware entropy scanner** — file-extension skip (`.glsl/.frag/.vert/.shader/.wgsl/.css/.scss/.sass/.less/.svg/.min.*/.map`) + 8 new line-suppression rules (GLSL keywords, CSS-in-JS templates, inline SVG, ffmpeg `filter_complex`, User-Agent strings, SQL DDL on dedicated lines, `throw new Error(\`...\`)`, markdown image URLs). Configurable via `.llm-security/policy.json` `entropy` section (thresholds, `suppress_extensions`, `suppress_line_patterns`, `suppress_paths`). Envelope `calibration` block reports skip counters + effective thresholds + policy source. **3. DEP typosquat allowlist expansion** — 22 npm + 5 PyPI entries for short-name tools that tripped Levenshtein on every modern codebase (`knip`, `oxlint`, `tsx`, `nx`, `rimraf`, `uv`, `ruff`, etc.). Synthesizer "Scan Calibration" section + "never override verdict" rule added. Legacy `riskScoreV1()` kept for reference. **CI pipelines with `--fail-on` thresholds may need recalibration.** 1487 tests (was 1461). |
 | **6.6.0** | 2026-04-18 | **JetBrains/IntelliJ plugin scanning.** `/security ide-scan` now covers JetBrains IDEs (IntelliJ IDEA, PyCharm, GoLand, WebStorm, RubyMine, PhpStorm, CLion, DataGrip, RustRover, Rider, Aqua, Writerside, Android Studio) — Fleet and Toolbox excluded. OS-aware discovery of `~/Library/Application Support/JetBrains/<IDE><version>/plugins/` (macOS), `%APPDATA%\JetBrains\...` (Windows), `~/.config/JetBrains/...` (Linux). Zero-dep parsers for `META-INF/plugin.xml` and `META-INF/MANIFEST.MF` with nested-jar extraction. 7 JetBrains-specific checks: theme-with-code, broad activation (`application-components`), `Premain-Class` instrumentation (HIGH — javaagent retransform), native binaries (`.so`/`.dylib`/`.dll`/`.jnilib`), long `<depends>` chains (supply-chain pressure), typosquat vs top JetBrains plugins, shaded-jar advisory. URL fetch for `plugins.jetbrains.com/plugin/<numericId>-<slug>` + direct `/plugin/download?pluginId=<xmlId>`; metadata resolves numericId → xmlId before download. `.kt`, `.groovy`, `.scala` added to `taint-tracer` code extensions. Reuses existing OS sandbox (`lib/vsix-sandbox.mjs` parameterized via `buildSandboxedWorker(..., workerPath)`). Knowledge: `knowledge/jetbrains-marketplace-api-notes.md`, expanded `knowledge/ide-extension-threat-patterns.md`, seeded `knowledge/top-jetbrains-plugins.json`. 1461 tests (was 1352). |
