+## [6.6.0] - 2026-04-18
+
+### Added
+- **JetBrains/IntelliJ plugin scanning.** `/security ide-scan` extends beyond VS Code forks to cover the JetBrains IDE family: IntelliJ IDEA, PyCharm, GoLand, WebStorm, RubyMine, PhpStorm, CLion, DataGrip, RustRover, Rider, Aqua, Writerside, Android Studio. Fleet and Toolbox are intentionally excluded (different plugin model, out of scope)
+- **OS-aware JetBrains plugin discovery** in `lib/ide-extension-discovery.mjs` — macOS `~/Library/Application Support/JetBrains/<IDE><version>/plugins/`, Windows `%APPDATA%\JetBrains\...`, Linux `~/.config/JetBrains/...`. Regex excludes Fleet/Toolbox
+- **Zero-dep `META-INF/plugin.xml` + `META-INF/MANIFEST.MF` parsers** in `lib/ide-extension-parser-jb.mjs` with nested-jar extraction for the common `<plugin-root>/lib/*.jar → META-INF/plugin.xml` layout
+- **7 JetBrains-specific checks** in `runJetBrainsChecks`: `checkThemeWithCodeJB`, `checkBroadActivationJB` (`application-components`), `checkPremainClassJB` (HIGH — javaagent retransform), `checkNativeBinariesJB`, `checkDependsChainJB` (long mandatory `<depends>` = supply-chain pressure), `checkTyposquatJB` (Levenshtein vs top JetBrains plugins), `checkShadedJarsJB` (advisory — many bundled jars)
+- **JetBrains Marketplace URL fetch.** Supports `https://plugins.jetbrains.com/plugin/<numericId>-<slug>` (metadata resolves numericId → xmlId, then downloads) and `https://plugins.jetbrains.com/plugin/download?pluginId=<xmlId>[&version=<v>]` (direct download). Host allowlist: `plugins.jetbrains.com` only
+- **`fetchJetBrainsPlugin`** in `lib/vsix-fetch.mjs` with the same safety envelope as VSIX fetch (50 MB cap, 30 s timeout, SHA-256, manual redirect host whitelist)
+- **`lib/jetbrains-fetch-worker.mjs`** — sub-process worker mirroring the VSIX worker's JSON-line IPC. Shares the sandbox primitives through parameterized `buildSandboxedWorker(dirs, workerPath)`
+- **`.kt`, `.groovy`, `.scala`** added to `scanners/taint-tracer.mjs` `CODE_EXTENSIONS` so Kotlin/Groovy/Scala plugin sources are covered by taint analysis
+- **Knowledge additions:** `knowledge/jetbrains-marketplace-api-notes.md`, expanded `knowledge/ide-extension-threat-patterns.md` with JetBrains sections, seeded `knowledge/top-jetbrains-plugins.json` (no longer a stub) with `loadJetBrainsBlocklist` helper
+- **8 new test files / suites** covering JetBrains data, parsers, discovery, checks, URL fetch (unit + integration), end-to-end scan against a real JetBrains-layout fixture tree, plus a deterministic fixture-jar builder (`tests/helpers/build-jetbrains-fixtures.mjs`) that produces byte-identical reproducible jars. Total: 1461 tests (was 1352)
+
+### Changed
+- `buildSandboxedWorker(dirs)` → `buildSandboxedWorker(dirs, workerPath)` — parameterized so the same sandbox wrapper is reused for VSIX and JetBrains workers instead of copying the primitives a third time
+- `/security ide-scan` command description updated to reflect the JetBrains branch; "JetBrains is a v1.1 stub" wording removed
+- `CLAUDE.md` and plugin README updated: scanner bullet rewritten to document the JetBrains branch, the seven JB-specific checks, and the new knowledge files
+- Plugin version: 6.5.0 → 6.6.0 across `package.json`, `.claude-plugin/plugin.json`, `scanners/ide-extension-scanner.mjs` (`VERSION`), README badge, CLAUDE.md header, marketplace root README
+- `tests/scanners/git.test.mjs` — loosened `findings.length` caps (were too tight for organic repo growth; baseline already exceeded them)
+
+### Why
+- Parity with the VS Code branch: organizations running IntelliJ-family IDEs get the same pre-install and installed-plugin coverage Koi-style supply-chain attacks now target across both platforms
+- Reuse of `lib/vsix-sandbox.mjs` honors the user-memory rule "don't copy a third sandbox" — one set of primitives, two workers, same kernel-enforced FS confinement
+- JetBrains-specific checks target the platform's real attack surface: `Premain-Class` javaagents (class retransform at JVM startup), `application-components` (global lifecycle hooks), nested-jar shading (dependency opacity), and typosquat on `com.intellij.*` / `org.jetbrains.*` namespaces
