## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 9 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 8.49.2
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

No source evidence shows malicious install-time mutation, stealth persistence, or credential theft. However, unverified server-directed binary download and execution is a meaningful unresolved RCE risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-07-29T14:41:25.426Z
- **Finished:** 2026-07-29T14:42:06.149Z
- **Download time:** 504 ms
- **Static scan time:** 1066 ms
- **AI review time:** 39152 ms
- **Total time:** 40723 ms

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:** During a BrowserStack-enabled test run, the service can download and execute a native CLI without integrity verification. This is a package-aligned but unresolved remote-code execution supply-chain surface.

- **Trigger:** A configured WebdriverIO BrowserStack session using the supported CLI path.

- **Impact:** A compromised update response or download host could execute arbitrary code as the test runner.

- **Evidence paths:** package.json, build/cli/cliUtils.js, build/cli/index.js, build/Percy/PercyBinary.js, build/ai-handler.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-29T14:42:06.149Z

### AI review details

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

- **Mechanism:** Server-directed binary download, extraction, chmod, and child-process spawn.

- **Rationale:** No source evidence shows malicious install-time mutation, stealth persistence, or credential theft. However, unverified server-directed binary download and execution is a meaningful unresolved RCE risk.

- **Files touched:** build/cli/cliUtils.js, build/cli/index.js, build/Percy/PercyBinary.js

- **Network endpoints:** https://api.browserstack.com, https://github.com/percy/cli/releases/latest/download

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** build/cli/cliUtils.js downloads a CLI archive from a server-provided URL with redirects enabled., The archive is extracted, chmodded executable, then spawned by build/cli/index.js., No checksum, signature, or archive-path validation is present in that download flow.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., CLI download/execution occurs during configured WebdriverIO test runtime, not installation or import., Observed endpoints are BrowserStack/Percy service endpoints aligned with the package purpose., AI code conditionally changes browser-test capabilities and installs a Firefox test-browser addon; it does not alter local AI-agent controls.

## Affected versions and remediation
