## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 11 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 17.8.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Static inspection found a normal Chromatic CLI package: no lifecycle hook, no import-time malicious behavior, and risky primitives are tied to explicit CLI build/upload workflows. Network telemetry/API use and child process execution are package-aligned and user-invoked.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-07-05T01:42:19.267Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Observed network, env, filesystem, and child-process behavior are aligned with a user-invoked Chromatic CLI that builds and uploads Storybook artifacts.

- **Trigger:** User runs chromatic/chroma CLI or imports package entrypoints

- **Impact:** Expected visual testing CLI behavior; no install-time persistence, credential harvesting, or agent control-surface mutation found

- **Evidence paths:** package.json, isChromatic.js, isChromatic.mjs, dist/bin.cjs, dist/node.cjs, dist/main-D2\_P43hc.cjs, dist/node-src-NjW8\_TQU.cjs, dist/build-CjuKDeXS.cjs, dist/execa-B9cO2acC.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-07-05T01:43:07.078Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Storybook build, metadata collection, upload, and service polling

- **Rationale:** Static inspection found a normal Chromatic CLI package: no lifecycle hook, no import-time malicious behavior, and risky primitives are tied to explicit CLI build/upload workflows. Network telemetry/API use and child process execution are package-aligned and user-invoked.

- **Files touched:** package.json, isChromatic.js, isChromatic.mjs, dist/bin.cjs, dist/node.cjs, dist/main-D2\_P43hc.cjs, dist/node-src-NjW8\_TQU.cjs, dist/build-CjuKDeXS.cjs

- **Network endpoints:** https://www.chromatic.com, https://status.chromatic.com, https://4fa173db2ef3fb073b8ea153a5466d28@o4504181686599680.ingest.us.sentry.io/4507930289373184

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle scripts; bin only maps chroma/chromatic/chromatic-cli to dist/bin.cjs, isChromatic.js and isChromatic.mjs only inspect browser userAgent/location for Chromatic markers, dist/bin.cjs dispatches explicit CLI subcommands and loads dotenv config; no install-time execution, dist/node-src-NjW8\_TQU.cjs network calls use Chromatic build/share APIs and user/project tokens for the CLI service, child\_process/execa use is for user-invoked Storybook/React Native build commands, not hidden execution, scanner unicode hit is bundled parser/entity Unicode tables in dist/build-CjuKDeXS.cjs, not Trojan Source control flow
