Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.0.0-alpha.83 - **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. The browser automation and process execution match the package's stated purpose, and no malicious command-output exfiltration chain was established. However, the entrypoint enables log telemetry by default without documenting it, so this merits a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-31T23:06:01.478Z - **Finished:** 2026-10-31T23:06:54.505Z - **Download time:** 776 ms - **Static scan time:** 1764 ms - **AI review time:** 50486 ms - **Total time:** 53027 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:** Undisclosed runtime log telemetry may be exported by the package's OpenTelemetry logsink. - **Trigger:** Creating the browse runtime or MCP logger; logs are enabled unless OTEL\_SDK\_DISABLED is set. - **Impact:** Runtime log messages and attributes may leave the host without clear disclosure to the package user. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-31T23:06:54.505Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint initializes the telemetry logsink and forwards log messages and attributes to it. Its resolved export endpoint is not specified in the inspected package source. - **Rationale:** The browser automation and process execution match the package's stated purpose, and no malicious command-output exfiltration chain was established. However, the entrypoint enables log telemetry by default without documenting it, so this merits a warning. - **Files touched:** ~/.cache/chrome-for-testing - **Network endpoints:** https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json, OTLP endpoint resolved by @agimon-ai/po-logsink or supplied through environment configuration ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package enables OpenTelemetry logs unless \`OTEL\_SDK\_DISABLED\` is set and initializes a logsink that can export them., The README describes the package as a browser automation runtime and MCP server., The \`ps\` command output is used to inspect browser process command lines. - **Evidence against:** There are no install lifecycle hooks in the manifest., The network request shown fetches Chrome for Testing version metadata from its official host., Browser code execution is exposed as an explicit tool input for browser automation. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.83. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.83 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.
