Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 15 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.47 - **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. Source inspection resolved the command-execution and dynamic-code signals to browser and custom-tool functionality. The package manifest has no install lifecycle hook, and the inspected entrypoints did not establish a concrete attack path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-25T05:00:47.607Z - **Finished:** 2026-10-25T05:01:36.176Z - **Download time:** 520 ms - **Static scan time:** 1694 ms - **AI review time:** 46353 ms - **Total time:** 48569 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 flagged process and dynamic-code behavior is consistent with browser automation and custom browser tooling. - **Trigger:** Consumers invoke the exported browser runtime or its browser-operation handlers. - **Impact:** These features enable browser automation; the inspected source did not establish credential theft, hidden data transfer, or persistence. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T05:01:36.176Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime launches a bound browser and supports custom browser code and configured local server commands. - **Rationale:** Source inspection resolved the command-execution and dynamic-code signals to browser and custom-tool functionality. The package manifest has no install lifecycle hook, and the inspected entrypoints did not establish a concrete attack path. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json points to the CommonJS and ESM browser-tool entrypoints; its scripts show build tasks, with no install lifecycle hook., Both entrypoints bind browser operations to a runtime profile and browser instance., The inspected port-registry dependency exposes port-allocation APIs through its entrypoints., The inspected process-registry dependency handles process lifecycle cleanup through its entrypoints., The inspected validator dependency uses Zod for schema validation., Process spawning serves browser launch and configured server operation; the dynamic code path is part of the browser tool’s custom-code feature. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.47. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.47 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.
