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 and runtime source show no install hook or confirmed attack behavior; the shell calls query display geometry, and the model request uses configured credentials for its API. Although candidate and message telemetry helpers target a fixed-default host, source searches found no activation path for them in this bundle. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T05:40:36.366Z - **Finished:** 2026-10-21T05:42:29.948Z - **Download time:** 776 ms - **Static scan time:** 1084 ms - **AI review time:** 111721 ms - **Total time:** 113582 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 active attack surface was identified in the inspected package source. The flagged process and network behavior supports browser display setup and configured model requests; the recruitment event helpers have no call sites in the bundle. - **Trigger:** The package entrypoint runs as the browser-use agent runtime; no trigger for the recruitment event helpers was found. - **Impact:** No confirmed credential theft, data exfiltration, or destructive behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T05:42:29.948Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected process calls query local display dimensions, and the model request uses a configured API key. The event sender requires configuration but has no reachable caller in the bundle. - **Rationale:** The manifest and runtime source show no install hook or confirmed attack behavior; the shell calls query display geometry, and the model request uses configured credentials for its API. Although candidate and message telemetry helpers target a fixed-default host, source searches found no activation path for them in this bundle. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest selects dist/index.js as the runtime entrypoint and lists no preinstall, install, or postinstall hook., The runtime child-process calls query local display geometry for browser window placement, with timeouts., The model API request sends model state and questions to api.typesafe.ai using a configured API key., The recruitment event sender requires an API token and agent ID; source searches found no call sites for its event helper functions in the bundle., The prepared browser dependency is a same-vendor browser runtime; its source imports child-process and browser automation components., The reply-authority client requires configured service URL and bearer token; the SDK passes model requests to its connected MCP server. - **Evidence against:** The bundle contains a fixed-default recruitment-event collector and payload builders for candidate details, message previews, sent message content, and WeChat numbers. The helpers have no call sites in the inspected bundle, and the sender checks for a token and agent ID before posting. ## Affected versions and remediation This report applies to @roll-agent/browser-use-agent@0.27.3. - Review the evidence and your use of @roll-agent/browser-use-agent@0.27.3 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.
