Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 0.0.0-alpha.8 - **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. The manifest has no install lifecycle hook, and the flagged subprocess behavior is tied to browser startup diagnostics or an explicitly enabled, configured web server. The inspected network request serves Chrome version lookup; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T12:30:08.621Z - **Finished:** 2026-10-17T12:31:12.267Z - **Download time:** 1012 ms - **Static scan time:** 2014 ms - **AI review time:** 60618 ms - **Total time:** 63646 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:** No attack was identified. The inspected network request retrieves Chrome for Testing metadata, and captured process output is used for bounded browser startup diagnostics. - **Trigger:** Browser operations run through the runtime API; starting a configured web server requires the startServer option. - **Impact:** No unauthorized data transfer or install-time mutation was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T12:31:12.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The web server command is read from Playwright configuration. Browser startup output is capped and included in failure diagnostics; no unrelated outbound transfer was found. - **Rationale:** The manifest has no install lifecycle hook, and the flagged subprocess behavior is tied to browser startup diagnostics or an explicitly enabled, configured web server. The inspected network request serves Chrome version lookup; no concrete attack behavior was established. - **Files touched:** package.json, dist/index.cjs, dist/index.mjs, dist/dockerChromeForTesting-BMmEQq88.mjs, dist/container-D-D4x8I7.mjs, dist/container-DrE51Rho.cjs - **Network endpoints:** https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json lists runtime entrypoints and no install lifecycle hook., Both runtime entrypoints dispatch browser operations with checks binding the browser to its profile and type., The Chrome helper fetches version metadata from the Google Chrome for Testing feed., Browser startup stdout and stderr are capped at 32 KiB and used in startup failure diagnostics., A web server command comes from Playwright configuration and starts only when the runtime startServer option is enabled. - **Evidence against:** The package can spawn processes, including a shell for the configured web server; the inspected path depends on runtime configuration and an explicit startServer option., The Chrome helper makes a network request to retrieve browser version metadata. No unrelated recipient or data transfer was identified. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.8. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.8 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
