fix: security audit remediation — 12 fixes, 20 tests (v0.13.1.0) (#595) * fix: remove auth token from /health, secure extension bootstrap (CRITICAL-02 + HIGH-03) - Remove token from /health response (was leaked to any localhost process) - Write .auth.json to extension dir for Manifest V3 bootstrap - sidebar-agent reads token from state file via BROWSE_STATE_FILE env var - Remove getToken handler from extension (token via health broadcast) - Extension loads token before first health poll to prevent race condition * fix: require auth on cookie-picker data routes (CRITICAL-01) - Add Bearer token auth gate on all /cookie-picker/* data/action routes - GET /cookie-picker HTML page stays unauthenticated (UI shell) - Token embedded in served HTML for picker's fetch calls - CORS preflight now allows Authorization header * fix: add state file TTL and plaintext cookie warning (HIGH-02) - Add savedAt timestamp to state save output - Warn on load if state file older than 7 days - Auto-delete stale state files (>7 days) on server startup - Warning about plaintext cookie storage in save message * fix: innerHTML XSS in extension content script and sidepanel (MEDIUM-01) - content.js: replace innerHTML with createElement/textContent for ref panel - sidepanel.js: escape entry.command with escapeHtml() in activity feed - Both found by security audit + Codex adversarial red team * fix: symlink bypass in validateReadPath (MEDIUM-02) - Always resolve to absolute path first (fixes relative path bypass) - Use realpathSync to follow symlinks before boundary check - Throw on non-ENOENT realpathSync failures (explicit over silent) - Resolve SAFE_DIRECTORIES through realpathSync (macOS /tmp → /private/tmp) - Resolve directory part for non-existent files (ENOENT with symlinked parent) * fix: freeze hook symlink bypass and prefix collision (MEDIUM-03) - Add POSIX-portable path resolution (cd + pwd -P, works on macOS) - Fix prefix collision: /project-evil no longer matches /project freeze dir - Use trailing slash in boundary check to require directory boundary * fix: shell script injection in gstack-config and telemetry (MEDIUM-04) - gstack-config: validate keys (alphanumeric+underscore only) - gstack-config: use grep -F (fixed string) instead of -E (regex) - gstack-config: escape sed special chars in values, drop newlines - gstack-telemetry-log: sanitize REPO_SLUG and BRANCH via json_safe() * test: 20 security tests for audit remediation - server-auth: verify token removed from /health, auth on /refs, /activity/* - cookie-picker: auth required on data routes, HTML page unauthenticated - path-validation: symlink bypass blocked, realpathSync failure throws - gstack-config: regex key rejected, sed special chars preserved - state-ttl: savedAt timestamp, 7-day TTL warning - telemetry: branch/repo with quotes don't corrupt JSON - adversarial: sidepanel escapes entry.command, freeze prefix collision * chore: bump version and changelog (v0.13.1.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: tone down changelog — defense in depth, not catastrophic bugs Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
feat: v0.3.2 — project-local state, diff-aware QA, Greptile integration (#36) * fix: cookie import picker returns JSON instead of HTML jsonResponse() was defined at module scope but referenced `url` which only existed as a parameter of handleCookiePickerRoute(). Every API call crashed, the catch block also crashed, and Bun returned a default HTML page that the frontend couldn't parse as JSON. Thread port via corsOrigin() helper and options objects. Add route-level tests to prevent this class of bug from shipping again. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add help command to browse server Agents that don't have SKILL.md loaded (or misread flags) had no way to self-discover the CLI. The help command returns a formatted reference of all commands and snapshot flags. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: version-aware find-browse with META signal protocol Agents in other workspaces found stale browse binaries that were missing newer flags. find-browse now compares the local binary's git SHA against origin/main via git ls-remote (4hr cache), and emits META:UPDATE_AVAILABLE when behind. SKILL.md setup checks parse META signals and prompt the user to update. - New compiled binary: browse/dist/find-browse (TypeScript, testable) - Bash shim at browse/bin/find-browse delegates to compiled binary - .version file written at build time with git commit SHA - Build script compiles both browse and find-browse binaries - Graceful degradation: offline, missing .version, corrupt cache all skip check Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: clean up .bun-build temp files after compile bun build --compile leaves ~58MB temp files in the working directory. Add rm -f .*.bun-build to the build script to clean up after each build. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: make help command reachable by removing it from META_COMMANDS help was in META_COMMANDS, so it dispatched to handleMetaCommand() which threw "Unknown meta command: help". Removing it from the set lets the dedicated else-if handler in handleCommand() execute correctly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: bump version and changelog (v0.3.2) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add shared Greptile comment triage reference doc Shared reference for fetching, filtering, and classifying Greptile review comments on GitHub PRs. Used by both /review and /ship skills. Includes parallel API fetching, suppressions check, classification logic, reply APIs, and history file writes. * feat: make /review and /ship Greptile-aware /review: Step 2.5 fetches and classifies Greptile comments, Step 5 resolves them with AskUserQuestion for valid issues and false positives. /ship: Step 3.75 triages Greptile comments between pre-landing review and version bump. Adds Greptile Review section to PR body in Step 8. Re-runs tests if any Greptile fixes are applied. * feat: add Greptile batting average to /retro Reads ~/.gstack/greptile-history.md, computes signal ratio (valid catches vs false positives), includes in metrics table, JSON snapshot, and Code Quality Signals narrative. * docs: add Greptile integration section to README Personal endorsement, two-layer review narrative, full UX walkthrough transcript, skills table updates. Add Greptile training feedback loop to TODO.md future ideas. * feat: add local dev mode for testing skills from within the repo bin/dev-setup creates .claude/skills/gstack symlink to the working tree so Claude Code discovers skills locally. bin/dev-teardown cleans up. DEVELOPING_GSTACK.md documents the workflow. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: narrow gitignore to .claude/skills/ instead of all .claude/ Avoids ignoring legitimate Claude Code config like settings.json or CLAUDE.md. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: rename DEVELOPING_GSTACK.md to CONTRIBUTING.md Rewritten as a contributor-friendly guide instead of a dry plan doc. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: explain why dev-setup is needed in CONTRIBUTING.md quick start Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add browser interaction guidance to CLAUDE.md Prevents Claude from using mcp__claude-in-chrome__* tools instead of /browse. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add shared config module for project-local browse state Centralizes path resolution (git root detection, state dir, log paths) into config.ts. Both cli.ts and server.ts import from it, eliminating duplicated PORT_OFFSET/BROWSE_PORT/STATE_FILE logic. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: rewrite port selection to use random ports Replace CONDUCTOR_PORT magic offset and 9400-9409 scan with random port 10000-60000. Atomic state file writes, log paths from config module, binaryVersion field for auto-restart on update. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: move browse state from /tmp to project-local .gstack/ CLI now uses config module for state paths, passes BROWSE_STATE_FILE to spawned server. Adds version mismatch auto-restart, legacy /tmp cleanup with PID verification, and removes stale global install fallback. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: update crash log path reference to .gstack/ Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * test: add config tests and update CLI lifecycle test 14 new tests for config resolution, ensureStateDir, readVersionHash, resolveServerScript, and version mismatch detection. Remove obsolete CONDUCTOR_PORT/BROWSE_PORT filtering from commands.test.ts. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: update BROWSER.md and TODO.md for project-local state Replace /tmp paths with .gstack/, remove CONDUCTOR_PORT docs, document random port selection and per-project isolation. Add server bundling TODO. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: update README, CHANGELOG, and CONTRIBUTING for v0.3.2 - README: replace Conductor-aware language with project-local isolation, add Greptile setup note - CHANGELOG: comprehensive v0.3.2 entry with all state management changes - CONTRIBUTING: add instructions for testing branches in other repos Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add diff-aware mode to /qa — auto-tests affected pages from branch diff When on a feature branch, /qa now reads git diff main, identifies affected pages/routes from changed files, and tests them automatically. No URL required. The most natural flow: write code, /ship, /qa. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: update CHANGELOG for complete v0.3.2 coverage Add missing entries: diff-aware QA mode, Greptile integration, local dev mode, crash log path fix, README/SKILL.md updates.
