# @agimon-ai/po-browse-tool@0.0.0-alpha.91 npm security report

## 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.91
- **Selected version is latest:** Yes
- **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 package enables runtime telemetry by default and the README does not disclose it, which meets the warning criteria for undisclosed runtime telemetry. The destination and complete payload are delegated to a dependency or OTLP configuration, so the source does not support a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 82.0%
- **Started:** 2026-11-01T23:40:36.506Z
- **Finished:** 2026-11-01T23:41:29.274Z
- **Download time:** 765 ms
- **Static scan time:** 1764 ms
- **AI review time:** 50238 ms
- **Total time:** 52768 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 telemetry is enabled by default when the host creates a browse runtime.

- **Trigger:** A host calls the exported createBrowseRuntime function; telemetry records are forwarded when logging occurs.

- **Impact:** Runtime log and exception attributes may be sent to a telemetry collector without the package documenting this behavior; the source does not establish whether they contain sensitive values.

- **Evidence paths:** dist/index.cjs, package.json, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-11-01T23:41:29.274Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The runtime initializes @agimon-ai/po-logsink with logs enabled unless OTEL\_SDK\_DISABLED is set. The collector is selected by that dependency or OTLP environment configuration, so the package source does not identify a fixed destination or complete payload.

- **Rationale:** The package enables runtime telemetry by default and the README does not disclose it, which meets the warning criteria for undisclosed runtime telemetry. The destination and complete payload are delegated to a dependency or OTLP configuration, so the source does not support a malicious verdict.

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 82.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Runtime logs are enabled unless OTEL\_SDK\_DISABLED is set to 1 or true., The runtime passes package and workspace details to @agimon-ai/po-logsink, enabling its telemetry with logs and traces., Log records are forwarded to the telemetry logger with attributes and exception details.

- **Evidence against:** The package is a browser automation runtime, and its main entrypoints are library exports with no install lifecycle scripts., The README describes the package’s browser automation and MCP server purpose., The telemetry destination is delegated to the logging dependency or OTLP environment configuration; this source does not establish a fixed collector host or the data ultimately sent.

## Affected versions and remediation

This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.91.

- Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.91 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.
