Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 0.12.2 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Static inspection found a browser-automation product with local profile handling and credit-service requests, but no lifecycle hook, stealth persistence, payload execution, or concrete credential/page-data exfiltration. The scanner's exfiltration label is not supported by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-08T09:58:34.237Z - **Finished:** 2026-09-08T10:00:09.215Z - **Download time:** 505 ms - **Static scan time:** 602 ms - **AI review time:** 93870 ms - **Total time:** 94978 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 confirmed malicious attack surface was established. Sensitive browser automation is invoked through the package commands, with no install-time execution or confirmed external data-exfiltration path. - **Trigger:** A user or configured MCP client invokes the Reflex CLI or MCP server. - **Impact:** The tool can access browser data within its local automation profile, but the inspected source did not establish unconsented transmission of that data. - **Review source:** ai\_review - **Reviewed:** 2026-09-08T10:00:09.215Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local Playwright-based browser automation and profile management. - **Rationale:** Static inspection found a browser-automation product with local profile handling and credit-service requests, but no lifecycle hook, stealth persistence, payload execution, or concrete credential/page-data exfiltration. The scanner's exfiltration label is not supported by the inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package provides sensitive local browser automation and Chrome-profile handling, so its runtime paths warranted review. - **Evidence against:** package.json declares only command-line entry points and no preinstall, install, or postinstall hook., The reviewed network code is for Reflex authentication, health checks, and aggregated credit metering; no source path was found sending page contents, cookies, or harvested credentials to an external host., Browser actions, profile copying, and daemon startup occur through the CLI or MCP runtime rather than during package installation or import. ## Affected versions and remediation This report applies to reflex-browser@0.12.2. - Review the evidence and your use of reflex-browser@0.12.2 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.
