feat(llm-security): v7.0.0 commit 7 — rule 18 (markdown image URL suppression)
E2E verification against content-heavy repo (`content-claude-code`) revealed 413 entropy findings (8 HIGH / 405 MEDIUM) from markdown image CDN URLs in JSON content indexes — e.g., ``. These are legitimate content-repo artifacts, not credentials. The 40-char hash segment in the CDN URL trips Shannon entropy (H=5.29 over 300 chars), and rule 13 (inline <svg>) doesn't match since there's no literal `<svg>` tag — the `.svg` is just a URL path suffix. Added rule 18 `MARKDOWN_IMAGE = /!\[[^\]]*\]\(\s*https?:\/\//` — matches `` / ``. Line-level (not string-level) so URL is not over-specific. E2E impact on `content-claude-code`: - Before: BLOCK / 65 / 8H 437M 0L - After: WARNING / 56 / 3H 427M 0L Hyperframes unchanged: BLOCK / 80 / 1C 4H 92M — real CRITICAL SQL-injection and HIGH findings still detected. Tests: 2 new (positive + negative fixture) bringing entropy-context to 26, total suite 1485 → 1487. Docs updated to "rules 11-18" and "8 new line-suppression rules".

| **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`) + 7 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(\`...\`)`). 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.** 1485 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). |

| **6.5.0** | 2026-04-17 | **OS sandbox for `/security ide-scan <url>`.** VSIX fetch + extract now runs in a sub-process wrapped by `sandbox-exec` (macOS) or `bwrap` (Linux), reusing the same primitives proven by the v5.1 git-clone sandbox. Defense-in-depth — even if `lib/zip-extract.mjs` ever has a bypass, the kernel refuses any write outside the per-scan temp directory. New: `lib/vsix-fetch-worker.mjs` (sub-process worker with deterministic JSON-line IPC) and `lib/vsix-sandbox.mjs` (`buildSandboxProfile` / `buildBwrapArgs` / `buildSandboxedWorker` / `runVsixWorker`, 35 s timeout, 1 MB stdout cap). New `scan(target, { useSandbox })` option (default `true` for CLI; tests use `false` since `globalThis.fetch` mocks do not cross processes). Windows fallback: in-process with `meta.warnings` advisory. Envelope `meta.source.sandbox` field: `'sandbox-exec' \| 'bwrap' \| 'none' \| 'in-process'`. 1352 tests (was 1344). |
|
||||
| **6.4.0** | 2026-04-17 | **`/security ide-scan <url>` — pre-install verification.** The IDE extension scanner now accepts URLs and fetches the VSIX before scanning. Supported: VS Code Marketplace (`https://marketplace.visualstudio.com/items?itemName=publisher.name`), OpenVSX (`https://open-vsx.org/extension/publisher/name[/version]`), and direct `.vsix` URLs. New libraries: `lib/vsix-fetch.mjs` (HTTPS-only fetch with 50MB cap, 30s timeout, SHA-256, manual host-whitelisted redirects) and `lib/zip-extract.mjs` (zero-dep ZIP parser, rejects zip-slip / symlinks / absolute paths / drive letters / encrypted entries / ZIP64; caps: 10 000 entries, 500MB uncompressed, 100x expansion ratio, depth 20). Temp dir always cleaned in `try/finally`. Envelope `meta.source` carries `{ type: "url", kind, url, finalUrl, sha256, size, publisher, name, version }`. New knowledge file: `marketplace-api-notes.md`. GitHub repo URLs intentionally not supported (would require a build step). 1344 tests (was 1296). |
