Installation downloads a declared Playwright browser dependency; root Linux installs may request browser system dependencies. At runtime, authenticated bridge requests can update supported AI-tool configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 85.0% - **Started:** 2026-08-09T02:13:17.681Z - **Finished:** 2026-08-09T02:14:16.508Z - **Download time:** 505 ms - **Static scan time:** 1514 ms - **AI review time:** 56807 ms - **Total time:** 58827 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation downloads a declared Playwright browser dependency; root Linux installs may request browser system dependencies. At runtime, authenticated bridge requests can update supported AI-tool configuration. - **Trigger:** npm postinstall; then authenticated/local runtime API requests. - **Impact:** Browser/runtime setup and deliberate configuration changes to supported local AI tools. - **Evidence paths:** package.json, scripts/ensure-bin-executable.mjs, scripts/ensure-playwright-browser.mjs, dist/middleware/auth.js, dist/config.js, dist/services/ai-source-apply.js, package/cc-switch-sdk/dist/services/ai-config-service.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T02:14:16.508Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Playwright provisioning and guarded agent-configuration integration. - **Rationale:** The package has real privileged integration behavior that merits a warning, but inspected lifecycle code does not mutate AI-agent control surfaces and no stealth, exfiltration, or payload execution was found. - **Files touched:** dist/index.js, scripts/ensure-playwright-browser.mjs, ~/.claude/settings.json, ~/.claude.json, ~/.codex/config.toml, ~/.config/opencode/opencode.json, ~/.acode/config.json - **Network endpoints:** https://npmmirror.com/mirrors/playwright, https://registry.npmjs.org/aws-runtime-bridge/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json postinstall runs browser setup., scripts/ensure-playwright-browser.mjs downloads Chromium and may request Playwright system dependencies as root., Runtime service can apply Claude, Codex, OpenCode, and Acode configuration through guarded APIs. - **Evidence against:** Postinstall only chmods its own dist/index.js and invokes the bundled Playwright CLI., Browser download behavior is explicit, opt-outable, and errors do not block installation., dist/middleware/auth.js protects privileged runtime routes with a pairing token, connection key, or panel session., No credential harvesting, hidden exfiltration, remote payload execution, or install-time AI-agent config mutation was found. ## Public findings ### 1.
